(7 points) It is an open secret that airlines overbook flights, but I have just learned recently that bookstores underbook (I might have invented this new term.) textbooks……….
To make a long story short, our UMUC designated virtual bookstore, MBS Direct, routinely, as a matter of business practice, orders less textbooks than the amount requested by UMUC’s Registrar’s Office. That is what I have figured out……. Simply put, MBS Direct has to “eat” the books if they are not sold. Do you want to eat the books? You may want to cook the books before you eat them! Oops, I hope there is no account major in this class?
OK, let us cut to the chase….. MBS Direct believes that only 85% of our registered students will stay registered in a class long enough to purchase the required textbook. Let’s pick on our STAT 200 students. According to the Registrar’s Office, we have 600 students enrolled in STAT 200 this spring 2014.
Suppose you are the CEO of MBS Direct, and you want to perform a probability analysis. What would be the number of STAT 200 textbook bundles you would order so that you stay below 5% probability of having to back-order from Pearson Custom Publishing? (Note: Our Provost would be very angry when she hears that textbook bundles have to be back-ordered. In any case, by next fall, we will no longer need the service of MBS Direct as we are moving 100% to free eResources. Auf Wiedersehen, MBS Direct……)
You already know that the exact solution is based on the binomial distribution. However, is there an approximate method to carry out the analysis in this Quiz #2 question? If so, how would you do it?
2. (7 points) In this recession, yours truly, CEO of the Outrageous Products Enterprise, would like to make extra money to support my frequent filet-mignon-and-double-lobster-tail dinner habit. A promising enterprise is to mass-produce tourmaline wedding rings for brides. Based on my diligent research, I have found out that women’s ring size normally distributed with a mean of 6.0, and a standard deviation of 1.0. I am going to order 5000 tourmaline wedding rings from my reliable Siberian source. They will manufacture ring size from 4.0, 4.5, 5.0, 5.5, 6.0, 6.5, 7.0, 7.5, 8.0, 8.5, 9.0, and 9.5. How many wedding rings should I order for each of the ring size should I order 5000 rings altogether? (Note: It is natural to assume that if your ring size falls between two of the above standard manufacturing size, you will take the bigger of the two.)
3. (6 points) An amusement park is considering the construction of an artificial cave to attract visitors. The proposed cave can only accommodate 36 visitors at one time. In order to give everyone a realistic feeling of the cave experience, the entire length of the cave would be chosen such that guests can barely stand upright for 98% of the all the visitors.
The mean height of American men is 70 inches with a standard deviation of 2.5 inches. An amusement park consultant proposed a height of the cave based on the 36-guest-at-a-time capacity. Construction will commence very soon.
The park CEO has a second thought at the last minute, and asks yours truly if the proposed height is appropriate. What would be the proposed height of the amusement park consultant? And do you think that it is a good recommendation? If not, what should be the appropriate height? Why?
4. (5 points) The amount of milk placed in cartons by filling machine has approximation of normal distribution. The mean is 64.3 onces and standard deviation of 0.12 ounces. Calculate probability that a carton will fill have less than 64 ounces.
5. (6 points) 91% of the 1860 Americans said that they would rather own a home than drive an expensive car. Please use the result of this survey to estimate with 98% confidence interval of percentage of all Americans who prefer homeownership to a more expensive automobile.
6. (5 points) For a random sample of 15 withdrawals from an automated teller machine, the average withdrawal was $115.00 and standard deviation was $25.00. Obtain a 95% confidence interval to estimate the true mean amount of withdrawal per transaction from the teller machine.
The following information is for Questions 7 through 12.
The recommended daily allowance (RDA) of cobalamine (Vitamin B12) for growing teens is 2.4 μg (micrograms). It is generally believed that growing teens are getting less than the RDA of 2.4 μg of cobalamine daily. A not-to-be-named Pharmaceutical (ntbnP) peddles dietary supplements around the country. It is claimed by ntbnP representatives that by taking their vitamin supplement, teens will have the RDA of cobalamine. FDA is going to take on ntbnP to show that the supplement comes short of providing teens with the recommended RDA.
FDA managed to collect with a 24-hour period blood sample of 10 randomly selected teens around the country. The amounts of cobalamine (in μg) determined in these 10 randomly selected teens are given as follow:
1.85 2.35 1.87 1.90 1.37 2.35 2.55 2.28 1.95 2.49
Based on their national experience, FDA assumes that the the population standard deviation of cobalamine in teens to be 0.56 μg.
Now, you are asked to weigh in on the dispute between FDA and ntbnP.
7. (3 points) Given the above information, what kind of hypothesis test will you conduct? Should it be α-test, z-test, t-test, χ2-test, F-test, or Ω-test? Please explain.
8. (3 points) What will be the null hypothesis, the alternative hypothesis, and, hence, the “tailedness” of the test (left-tailed, right-tailed, or two-tailed)?
9. (7 points) What is be the corresponding test statistics?
10. (5 points) What is the corresponding p-value of the hypothesis test?
11. (9 points) What kind of conclusion can you draw from the hypothesis test you have just performed? Of course, representatives of ntbnP would like to have the conclusion skewed to their advantage. And so would the officials from FDA. What would you do if you are representing ntbnP? But, if you are representing FDA, how would you present your argument?
12. (7 points) But, wait. What if FDA actually does not know the population standard deviation in this case, would you conduct your hypothesis test different? Just in case that you are going to perform the hypothesis different, what would you do instead?

I’ve attached the instructions

I’ve attached a sample of the survey all the students used and our instructor compilied into a excel spread sheet.Â

It’s important the expertise understands all parts of the assignment.Â

I’m looking for an expert in mathmatics, science and/or statistics. (between-subjects design)

Psychology students need to learn how to look at each factor within a study and the interaction between those factors. This assignment will assist students in learning how to understand this concept:

Â

For this assignment, you will test the following hypotheses:

a) Frequent users of Facebook will have a significantly different level of self-esteem than infrequent users of Facebook.

Locate all the answers to the questions specifically about Facebook use:

i)  Facebook Question #s-

(1)  2, 3, 4, 7, 18, and 23

ii)  For each individual, average their scores from the above 6 numbers to create only ONE number representing Facebook use

(1 Definition of Frequent users– an average Facebook number of 2.5 or more.

(  Definition of Infrequent users– an average Facebook number less than 2.5.

2) Module 2: Part I – Survey

a Each team member will access and complete the “Facebook Survey.â€Â Send your results to the professor via the individual forum.

FROM THIS POINT DOWN NEEDS TO BE COMPLETED.Â

Write a program that calculates the balance of a savings account at the end of a three-
month period. It should ask the user for the starting balance and the annual interest
rate. A loop should then iterate once for every month in the period, performing the
following steps:
A) Ask the user for the total amount deposited into the account during that month
and add it to the balance. Do not accept negative numbers.
B) Ask the user for the total amount withdrawn from the account during that
month and subtract it from the balance. Do not accept negative numbers or
numbers greater than the balance after the deposits for the month have been
added in.
C) Calculate the interest for that month. The monthly interest rate is the annual
interest rate divided by 12. Multiply the monthly interest rate by the average of
that month’s starting and ending balance to get the interest amount for the
month. This amount should be added to the balance.
After the last iteration, the program should display a report that includes the following
information:
• starting balance at the beginning of the three-month period
• total deposits made during the three months
• total withdrawals made during the three months
• total interest posted to the account during the three months
• final balance

Developers use the system development life cycle to map out a project from the planning phase to maintenance. In information systems, change is required to implement new software or hardware. How can the system development life cycle be used for changing from a brick-and-mortar store to creating an online presence?

A project manager can use project management to create a plan for change. What are some of the reasons a project may fail or succeed? What steps can be put into place to ensure success and limit failed attempts? Provide specific examples from the textbook or other sources to support your answer.
