A Food Marketing Institute found that 28% of households spend more than $125 a week on groceries. Assume the population proportion is 0.28 and a simple random sample of 436 households is selected from the population. What is the probability that the sample proportion of households spending more than $125 a week is less than 0.3?

There is a  probability that the sample proportion of households spending more than $125 a week is less than 0.3. Round the answer to 4 decimal places.to find answer

QUESTION PART A: You want to obtain a sample to estimate a population proportion. At this point in time, you have no reasonable estimate for the population proportion. You would like to be 99.9% confident that you esimate is within 1.5% of the true population proportion. How large of a sample size is required?

n =

QUESTION PART B: If n = 300 and ˆp (p-hat) = 0.3, construct a 90% confidence interval.

Give your answers to three decimals

_____< p < _____

QUESTION PART C: Many investors and financial analysts believe the Dow Jones Industrial Average (DJIA) gives a good barometer of the overall stock market. On January 31, 2006, 9 of the 30 stocks making up the DJIA increased in price (The Wall Street Journal, February 1, 2006). On the basis of this fact, a financial analyst claims we can assume that 30% of the stocks traded on the New York Stock Exchange (NYSE) went up the same day.

A sample of 53 stocks traded on the NYSE that day showed that 26 went up.

You are conducting a study to see if the proportion of stocks that went up is is significantly more than 0.3. You use a significance level of α=0.02α=0.02.

What is the test statistic for this sample? (Report answer accurate to three decimal places.)
test statistic =

What is the p-value for this sample? (Report answer accurate to four decimal places.)
p-value =

The p-value is...

• less than (or equal to) αα
• greater than αα

This test statistic leads to a decision to...

• reject the null
• accept the null
• fail to reject the null

As such, the final conclusion is that...

• There is sufficient evidence to warrant rejection of the claim that the proportion of stocks that went up is is more than 0.3.
• There is not sufficient evidence to warrant rejection of the claim that the proportion of stocks that went up is is more than 0.3.
• The sample data support the claim that the proportion of stocks that went up is is more than 0.3.
• There is not sufficient sample evidence to support the claim that the proportion of stocks that went up is is more than 0.3.

One of the major problems with front office accounting at the Royal Crest Hotel is monitoring guest and non-guest accounts using their manual system. Management has always extended local businesses and government officials charge privileges, the idea being that, with the convenience of deferred payments, local patrons would be more likely to dine and/or host clients at the hotel. This program has proved to be highly successful. The volume of purchases charged to such non-guest accounts now approximates the level of sales incurred by registered guests. Unsure if this is a good or bad situation, Mr. Osei, the front office manager, requests the front office accounting staff to study the problem and to report its findings at next week's front office meeting. At the weekly front office meeting, the hotel's accountant, Ms. Pokua, reports that there are at least three problems related to the hotel's non- guest charge purchasing policies: its impact on the daily hotel audit, the billing procedures to collect payment, and the number of applications for additional non-guest accounts. When asked to be more specific, she begins with a review of the daily hotel audit. She states that since the front office receives charge vouchers from the hotel's revenue centers, it is the front desk agent's responsibility to separate guest from non-guest accounts. Since registered guest charges are posted by room number, one would think it easy to sort those charges from the others. Unfortunately, both the hotel's guest account numbers and the non-guest account numbers are three digits, thereby making the sorting more time-consuming. Mr. Osei asks if it is really necessary to separate the charges. Ms. Pokua explains that it is, since the hotel must maintain accurate guest folio Page 2 of 1 G. N. Baah balances. She further states that the non-guest vouchers are accumulated and posted on Saturday afternoons, when the hotel's business is less hectic. The billing procedures to collect non-guest account balances are tricky, Ms. Pokua said. Since the hotel bills non-guest accounts on the last day of each month, some charges occurring in a particular month may not be posted in time to appear on that month's bill. In addition, non-guest accounts usually are not paid in time. In fact, 47 percent of last month's non-guest account balances remain unpaid and tomorrow is the date of the next billing cycle. Mr. Osei explains that the local customers are important to the hotel and suggests that maybe Ms. Pokua is over-sensitive to the billing problems. Lastly, Ms. Pokua relates the fact that there are at least ten new applications for non-guest accounts. She has instructed her staff not to authorize any new non-guest accounts without her written approval. She further states that she is reluctant to authorize any additional non-guest accounts, and looks to Mr. Osei for advice. Convinced of the positive aspects of such business, Mr. Osei directs her to approve the requests and to assign account numbers effective the first day of next month.

1). State four things that could be done to improve collection of outstanding balances? .    

2). What are the two (2) advantages and two (2) disadvantages to having a high volume of non- guest accounts? NOTE; PLEASE I NEED DIFFERENT ANSWERS.

• Our role: as a non-profit organization, the Coalition for the Homeless in NYC.

• Focus area: Mott Haven, Bronx

• Partner: Comfort Inn & Suites in Bronx, Family Shelter in Bronx, Government

• Solution:

  • We’re partnering with Comfort Inn & Suites in Bronx to give a room for homeless people that we have data and information to stay on one of the room.

  • Group of homeless that priority: family with children, single mom with children, elderly (60+), disability people.

  • We’re asking Comfort Inn & Suites to give us at least 15 rooms (out of 84) during the low season and 7 rooms during the high season. Each room can accomodate 2 to 3 people. So we can put at least 45 homeless people for one night.

  • Asking special rate: Normal rate is around $142 → $49 on low season and $99 on high season (for us)

  • Who pay: we will pay monthly and ask government to subsidize our program at least half of the total cost. Asking local religious institution such as churches, synagogues or mosques to participate in our program.     

How we select homeless?

1. We work together with Family Shelter Bronx to get the information of homeless people who still sleep outside the shelter

2. Working closely with HOME-STAT to have information for people that need immediate place to rest such as homeless with medical issue or disability.

3. Before we send the homeless people, at the shelter, we will give them food, ask them to shower and change clothes and check their health.

4. After that, we send them to the Comfort Inn & Suites to stay there for 1 week

5. During 1 week period, our staff will help them to find shelters in Bronx area or NYC’s area

6. We will help the homeless people to apply job, SOTA, or affordable housing in the NYC’s area.

7. If we can’t put them in the shelter within 1 week period, we will continue to pay their hotel fee for another week.

How the process in the hotel?

1. We will send the information first to the hotel of how many homeless will stay and give them their informations.

2. Each homeless that we selected need to give their ID in the reception.

3. The front desk will give the key to homeless on the assign room.

Problem 1: "Letter index"

Write a program that inputs a word and an unknown number of indices and prints the letters of the word corresponding to those indices. If the index is greater than the length of the word, you should break from your loop

Sample input:

apple 0 3 20

Sample output:

a l

Problem 2: "Matching letters"

Write a program that compares two words to see if any of their letters appear at the same index. Assume the words are of equal length and both in lower case. For example, in the sample below, a and e appear in both words at the same index.

Sample input:

apple andre

Sample output

a

e

Problem 3: "Word count"

You are given a series of lowercase words separated by spaces and ending with a . , all one on line. You are also given, on the first line, a word to look up. You should print out how many times that word occured in the first line.

Sample input:

is

computer science is no more about computers than astronomy is about telescopes .

Sample output:

2

Problem 4: "Treasure Chest"

The input to your program is a drawing of a bucket of jewels. Diamonds are represented as @, gold coins as $, rubies as *. Your program should output the total value in the bucket, assuming diamonds go for $1000, gold coins for $500, and rubies for $300. Note that the bucket may be wider or higher than the bucket in the example below.

Sample input:

|@* @ |

| *@@*|

|* $* |

|$$$* |

| *$@*|

-------

Sample output:

$9900

Problem 5: “Speed Camera”

Speed cameras are devices that monitor traffic and automatically issue tickets to cars going above the speed limit. They work by comparing two pictures of a car at a known time interval. If the car has traveled more than a set distance in that time, the car is given a citation.

The input are two text representations of a traffic picture with a car labeled as letters “c” (the car is moving upwards. These two pictures are shot exactly 1 second apart. Each row is 1/50 of a mile. The car is fined $10 for each mile per hour over 30 mph, rounded down to the nearest mph. Print the fine amount.

Sample input:

Problem 6. Distance from the science building

According to Google Maps, the DMF science building is at GPS coordinate 41.985 latitude, -70.966 longitude. Write a program that will read somebody’s GPS coordinate and tell whether that coordinate is within one-and-a-half miles of the science building or not.

Sample input:

-70.994

41.982

Sample output:

yes

At our position, 1 1/2 miles is about .030 degrees longitude, but about .022 degrees latitude. That means that you should calculate it as an ellipse, with the east and west going from -70.936 to -70.996, and the north and south going from 41.963 to 42.007.

Hint: Use the built in Ellipse2D.Double class. Construct a Ellipse2D.Double object using the coordinates given, and then use its "contains" method.

Problem 7: "Palindrome Numbers"

A palindrome is a word that reads the same forwards and backwards, such as, for example, "racecar", "dad", and "I". A palindrome number is the same idea, but applied to digits of a number. For example 1, 121, 95159 would be considered palindrome numbers.

The input to your program are two integers start and end. The output: all of the palindrome numbers between start and end (inclusive), each on a new line.

Sample input:

8 37

Sample output:

8

9

11

22

33

Hints:

1. Start by writing and testing a function that takes a number and returns true/false if the number is a palindrome. Then call that function in a for loop.

2. To see if a number is a palindrome, try turning it into a string. Then use charAt to compare the first and last digits, and so on.

Question 1 (1 point)

Airline companies recognize that empty seats represent lost revenues that can never be recovered. To avoid losing revenues, the companies often book more passengers than there are available seats. Then, when a flight experiences fewer no-shows than expected, some passengers are 'bumped' from their flights (are denied boarding). Incentives are provided to encourage passengers to give up their reserved seat voluntarily, but occasionally some passengers are involuntarily bumped from the flight. Obviously, these incidents can reflect poorly on customer satisfaction. Suppose Southwest Airlines would like to estimate the true proportion of involuntarily bumped passengers across all domestic flights in the industry. In a pilot sample of 863 domestic passengers, 259 were involuntarily bumped. What is the estimate of the population proportion and what is the standard error of this estimate?

0.8 g of mg metal was used in gas constant experiment. what will happen? will the r value be determine

Let x be a random variable that represents the weights in kilograms (kg) of healthy adult female deer (does) in December in a national park. Then x has a distribution that is approximately normal with mean μ = 70.0 kg and standard deviation σ = 7.3 kg. Suppose a doe that weighs less than 61 kg is considered undernourished.

(a) What is the probability that a single doe captured (weighed and released) at random in December is undernourished? (Round your answer to four decimal places.)


(b) If the park has about 2650 does, what number do you expect to be undernourished in December? (Round your answer to the nearest whole number.)
does

(c) To estimate the health of the December doe population, park rangers use the rule that the average weight of n = 45 does should be more than 67 kg. If the average weight is less than 67 kg, it is thought that the entire population of does might be undernourished. What is the probability that the average weight

x

for a random sample of 45 does is less than 67 kg (assuming a healthy population)? (Round your answer to four decimal places.)


(d) Compute the probability that

x

< 71.2 kg for 45 does (assume a healthy population). (Round your answer to four decimal places.)
