1) The first task is to review some information that might be useful later:

a) Write a brief definition of the word "quartile" as we have used it in previous weeks. Be sure to provide a citation: _____________________________.

b) Write a brief definition of the word "quantile" as it might be used in statistics. Be sure to provide a citation (do not cut and paste... use your own words to summarize what you discovered): ________________________________.

c) From within interactive R, enter the command shown below (the command shows a help page for the pbinom command). Provide a very brief description of the arguments that are passed to the pbinom() command ("arguments" in computer programming are the options that you give to a function so that the function can calculate what you want it to). Note that one of the arguments is lower.tail = TRUE, and because there is a value assigned to it with the equals sign, it means that if you do not enter a new value for lower.tail, it will be set to TRUE by default. Do not type the ">" into R, it is the command prompt:

> ?pbinom

2) You can use the dbinom() command (function) in R to determine the probability of getting 0 heads when you flip a fair coin four times (the probability of getting heads is 0.5):

dbinom(0, size=4, prob=0.5)

Find the equivalent values for getting 1, 2, 3, or 4 heads when you flip the coin four times. TIP: after you run the first dbinom() command, press the up arrow and make a small change and run it again.

probability of getting exactly 1 head: _______

probability of getting exactly 2 heads: _______

probability of getting exactly 3 heads: _______

probability of getting exactly 4 heads: _______

3) Use the pbinom() function in R to show the cumulative probability of getting 0, 1, 2, 3, or 4 heads when you flip the coin 4 times (this is the same as finding the probability than the value is less than or equal to 0, 1, 2, 3, or 4.)

probability of getting no more than 0 heads: ____

probability of getting no more than 1 head: _____

probability of getting no more than 2 heads:_____

probability of getting no more than 3 heads: ____

probability of getting no more than 4 heads: ____

4) The following R command will show the probability of exactly 6 successes in an experiment that has 10 trials in which the probability of success for each trial is 0.5:

dbinom(6, size=10, prob=0.5)
(True/False)____________

5) What is the probability of getting fewer than 2 heads when you flip a fair coin 3 times (round to 2 decimal places) ? ______

6) What is the probability of getting no more than 3 heads when you flip a fair coin 5 times (be sure to understand the wording differences between this question and the previous one—round to 2 decimal places)? ________

Information

The exponential distribution is a continuous distribution. The main R functions that we will use for the exponential distribution are pexp() and qexp(). Here is an example of the pexp() function. Leaves are falling from a tree at a rate of 10 leaves per minute. The rate is 10, or we can say that lambda = 10 (meaning 10 leaves fall per minute). The leaves do not fall like clockwork, so the time between leaves falling varies. If the time between leaves falling can be modeled with an exponential distribution, then the probability that the time between leaves falling will be less than 5 seconds (which is 5/60 of a minute) would be:

(note: this is an explanation of how pexp() works, you will answer a different question below)

pexp(5/60, rate=10)

which is about 0.565 (meaning that the probability is a bit higher than 50% that the next time-span between leaves falling will be less than 5 seconds).

For tasks 7-12, assume that the time interval between customers entering your store can be modeled using an exponential distribution. You know that you have an average of 4 customers per minute, so the rate is 4, or you can say that lambda =4.

It is easiest to keep everything in the original units of measurement (minutes), but you can also translate that to seconds because a rate of “4 customers per minute” is the same as “4 customer per 60 seconds,” and you can divide each number by 4 to get a rate of “1 customer per 15 seconds” or a rate of “1/15 customers per second.”

7) What is the expectation for the time interval between customers entering the store? Be sure to specify the units of measurement in your answer. Round to 3 decimal places: ___________________

8) What is the variance of the the time interval? Be sure to specify the units of measurement in your answer. Round to 3 decimal places:_________________

9) The pexp() function is introduced at the bottom of Yakir, 2011, p. 79, and there are some tips above. What is the probability that the time interval between customers entering the store will be less than 15.5 seconds. Be sure to enter values so that everything is in the same unit of measurement. Be sure to specify the units of measurement in your answer. Round your answer to 3 decimal places: _________________.

10) What is the probability that the time interval between customers entering the store will be between 10.7 seconds and 40.2 seconds?________

11) The qexp() function in R allows you to enter a probability, and it will tell you the criterion value (“cutoff point”) that corresponds to that probability value (e.g., if you enter .05 it tells you the cutoff point below which 5% of the values in the distribution fall).

What value of x would be the criterion value (cut-off point) for the top 5% of time intervals (Round to 3 decimal places, and include the units of measurement)? _______

---------------------------------

12) Describe in your own words the meaning of the number that the following R command produces (you are asked to interpret the resulting number so that we understand what that number means).

pexp(1.2, rate=3)

You have now had practice with the binomial distribution and the exponential distribution. The approach to solving problems for the normal distribution is similar to that for the exponential function, but obviously you use different R functions (usually pnorm() or qnorm()).

For the following three exercises, assume that you have a normally distributed random variable, called A, with a mean of 7, and a population standard deviation of 3.

13) What is the probability that a randomly selected value from variable A will be greater than 9?_______

14) What value of variable A would be the cutoff point (criterion value) for identifying the lowest 4% of values in variable A (use the qnorm function)?____________

15) What is the probability that a randomly selected value from variable A will be more than one standard deviation above its mean (there are couple ways to solve this, one way is to use the standard normal distribution?________________

Please show all work so I cam better understand and learn

Crazy Cliff’s Car Coral (CCCC) has an unusually large number of customers failing to make their car payments. Consequently, CCCC is considering investing in a GPS tracking system that will allow them to track and immobilize the cars when customers miss a payment. CCCC has already paid $10,000 in non-refundable fees necessary to get approval from the state. The system has an initial cost of $90,000 and a three-year useful life. CCCC depreciates all assets to zero using straight-line depreciation. The equipment has zero salvage value at the end of the project in 3 years. The new system also requires an additional investment in inventory of $6,000 at the beginning of the project (the inventory will be sold for $6,000 at the end of the project). CCCC estimates the new GPS system will save $60,000 per year in collection costs over the three-year life of the project. CCCC’s tax rate is 25% and the appropriate discount rate is 15%. What is the payback period of the project? What is the NPV of the project? What is the IRR of the project? Should CCCC accept the project?

Hamburgers are America’s favorite food. Consumers spend more than $100 billion on the beef sandwiches every year. But despite America’s infatuation with burgers, there is considerable dissatisfaction among consumers based on hamburger quality and value. Many customers just aren’t happy with what is served up at market-leading fast-food outlets. They want a better burger, and they won’t hesitate to pay a higher price to get one. Enter Smashburger. Started just a few years ago in Denver, Colorado, Smashburger is now a rapidly expanding chain of more than 100 stores in 17 states. And all this growth happened during a severe economic downturn despiteSmashburger’s average lunch check of $8. Many customers pay as much as $10 or $12 for a burger, fries, and shake. The Smashburgervideo shows how this small startup has pulled off a seemingly impossible challenge.

Discuss the three major pricing strategies in relation to Smashburger. Which of these three do you think is the company’s core strategic strategy?

What effect does Smashburger’s premium price have on consumer perceptions?

Is Smashburger’s success based on novelty alone or will it continue to succeed? Explain.

12.64  Do poets die young? According to William Butler Yeats, “She is the Gaelic muse, for she gives inspiration to those she persecutes. The Gaelic poets die young, for she is restless, and will not let them remain long on earth.’’ One study designed to investigate this issue examined the age at death for writers from different cultures and genders.21 Three categories of writers examined were novelists, poets, and nonfiction writers. Most of the writers are from the United States, but Canadian and Mexican writers are also included. ( DATA Below)
