distribution that would be appropriate to model the situation.
Additionally, if there is any information about the parameter
values, include those as well.
i) A pesticide is being tested on groups of plants. 10 experiments
are completed. Within each experiment a plant is sprayed with the
pesticide. After one week, the plant is assessed and categorized as
either dead or alive. Pesticides with similar chemicals have a 95%
survival rate.
ii) An athletic trainer is investigating the average mile time for
high school cross country runners. He looks at the data and
observes that it is approximately bell shaped with an average of 5
minutes and 45 seconds.
iii) An economist is looking at US income data. He would like to
use the Gaussian distribution, but notices the data is heavily
skewed.
iv) A mental health practitioner is examining the amount of time
(in months) that patients stick around in rehabilitation
facilities. They will treat the times as continuous. Literature
says that the average survival time is 0.75 months.
v) An engineer is looking to model the measurement error of a new
instrument. The error looks bell shaped and approximately symmetric
around 0.
vi) A popular game show, ”Deal or No Deal,” has 26 cases (numbered
1 to 26) that contain various amounts from $1 to $1,000,000. The
game starts by the contestant picking one of the cases to hold
onto. We are interested in a contestants initial selection.

There are new kinds of summer campus sprouting up for kids, with names like Camp Millionaire, MoolahU, and WhizBizKids. Rather than teaching basketball or camping skills, the camps appeal to parents who want to teach their children the basics of money management, or support budding Warren Buffetts and Steve Jobses who show an interest in business. The programs teach everything from basic financial concepts to how to launch a startup. The general idea for these campus is to teach kids early about money, investing and entrepreneurship. At MoolahU, a startup camp that launched in Austin, Texas in 2005, young business minds ages 7 to 17 collaborate for a week to develop a business idea and prototype product, and get a loan from a "barracuda tank" of local business experts-who include established businesspeople and entrepreneurs. From there, they sell their product, repay their borrowed money with interest and take turns occupying different leadership roles in their business. MoolahU's 3,000 alums can stay engaged beyond summer through a school-year apprentice program. At Camp Millionaire, youngsters learn that money can be earned through a salaried job or "made" by creating a business or income stream that delivers returns or passive income (rent, licensing fees, royalties, etc).

To what degree do you think you would have enjoyed and benefited from attending MoolahU when you were younger? |

You have recently been promoted to General Manager at Creekview Lodge, a 50 room hotel in Gatlinburg, Tennessee. You started working at the lodge in high school in the restaurant and after college, returned to Creekview as one of the assistant managers before being promoted to hotel manager. Recently, a 200-room hotel opened not far from Creekview Lodge, and although Creekview still maintains near 100% capacity there has been quite a bit of turnover. More than ten employees left to work for the larger hotel which boasted higher pay and better health insurance.
You were informed this morning by the front desk team that the latest customer survey results show a drop in the satisfaction rating for guest room cleanliness. The current report indicates that 73% of guests responded “completely satisfied”, 12% responded “satisfied”, 10% responded “neither satisfied nor unsatisfied”, and 5% responded “unsatisfied.” The housekeeping staff lost four employees to the new hotel, so although disappointed, you aren’t surprised by this news. Still, you could not remember a time that the hotel had received such a low satisfaction rating.
As manager of Creekview Lodge, what is your next step in addressing the problem?
A)Take immediate action and require that all rooms be inspected by the hotel manager (you) or an assistant manager before being made available to customers
D)Review the standards of performance and compare to current performance

The use of computers in education is referred to as computer-assisted instruction (CAI). More sophisticated CAI systems monitor the student’s performance over a period of time. The decision to begin a new topic is often based on the student’s success with previous topics. Modify the following auxiliary program (Computers are playing an increasing role in education. Write a program that will help an elementary school student learn multiplication. Use rand to produce two positive one-digit integers. It should then type a question such as: How much is 8 * 9? The student then types the answer. Your program checks the student’s answer. If it is correct, print “Very good!” and then ask another addition question. If the answer is wrong, print “No. Please try again.” and then let the student try the same question again repeatedly until the student finally gets it right. Terminate the program when the student has 5 right answers.) to count the number of correct and incorrect responses typed by the student. After the student types 5 answers, your program should calculate the percentage of correct responses. If the percentage is lower than 75 percent, your program should print “Please ask for extra help” and then terminate. If the percentage is 75 percent or higher, your program should print “Good work!” and then terminate.
I am programming student so please keep code simple enough that I can learn from it thanks

Imagine that you are preparing taxes for a local tax service provider. A married couple named Judy and Walter Townson have come to you to seeking assistance with their federal income taxes. During your meeting with the Townsons, you gather the following information: They are both 55 years of age. They have two daughters and one son. One daughter (age 25) is married with children. One daughter (age 20) is living at home and attending college. Their son (age 16) is a junior in high school. They are currently paying for their college-student daughter to attend school full time. Judy is employed as a teacher and makes $60,000 a year. She used $500 of her personal funds to purchase books and other supplies for her classroom. Walter is employed as a CPA and makes $100,000 a year. They provided you a 1099-INT which reported $4,500 in interest of which $500 was savings bond interest. They provided you a 1099-DIV which reported $300 in dividends. They received a state tax refund last year of $385. They provided you a list of expenses including: Doctor’s bills, $800 Prescriptions, $400 New glasses, $2000 Dental bills, $560 Braces, $5000 Property taxes for their two cars of $800, which included $50 in decal fees Real estate taxes of $4500 Mortgage interest of $12,000 Gifts to charities, $1000 GoFundMe contribution to local family in need, $100 Tax Preparation Fees for last year’s taxes, $400 Consider the most beneficial way for Judy and Walter to file their federal income tax return.

A consulting firm was hired to conduct a survey on people living in New York City. The survey was completed monthly for six months by 445 randomly-selected people in different boroughs. There were a number of items on the survey, but six basic biographical items will be studied for this exercise. The data for the people surveyed in one of these monthly surveys can be found in the Excel file SURVEY. The variables that were used for the basic biographical data are found on the last page of the exercise. In this exercise, some of the estimation techniques presented in the module will be applied to the New York survey results. You may assume that these respondents represent a simple random sample of all potential respondents within the community, and that the population is large enough that application of the finite population correction would not make an appreciable difference in the results. New York City governmental agency personnel like to have point estimates regarding variables describing the biographical information of the people living within the different boroughs. It is very helpful for them to have some idea regarding the likely accuracy of these estimates as well. Therein lies the benefit of the techniques presented in this module and applied here. • Item A in the description of the data collection instrument lists variables 1 through 5, which represent the respondent’s general attitude toward each of the five boroughs. Each of these variables has numerically equal distances between the possible responses, and for purposes of analysis they may be considered to be of the interval scale of measurement. • Determine the point estimate, and then construct the 95% confidence interval for μ1= the average attitude toward Manhattan. • Repeat part (a) for μ2 through μ5, the average attitudes toward Brooklyn, Queens, The Bronx and Staten Island, respectively. • Given the breakdown of responses for variable 6 (highest level of education), determine the point estimate, and then construct the 95% confidence interval for p6= the population proportion of doctoral degrees. • Given the breakdown of responses for variable 7 (marital status of respondent), determine the point estimate, and then construct the 95% confidence interval for p7 = the population proportion in the “single or other” category. • Assume the governmental agencies requested estimates of the mean attitudes towards each borough with a margin of error of 0.05 for each borough. If the governmental agency personnel want to have 95% confidence that the sample mean will fall within this margin of error, how large should the sample sizes be for each borough? The introduction should describe or summarize the topic or problem. It might discuss the general applications of the topic or it might introduce the unique terminology associated with the topic. o The body of your paper should address the questions posed in the problem. Explain how you approached and answered the question or solved the problem, and, for each question, show all steps involved. Be sure this is in paragraph format, not numbered answers like a homework assignment. o The conclusion should summarize your thoughts about what you have determined from your analysis in completing the assignment. Nothing new should be introduced in the conclusion that was not previously discussed in the body paragraphs. • Include any tables of data or calculations, calculated values, and/or graphs referenced in the paper. (Note: The minimum required length excludes any tables or graphs.) • A. General Attitude toward Each Borough (Variables 1–5) 1. Manhattan 2. Brooklyn 3. Queens 4. The Bronx 5.
