5. Expected Value of Sample Information (16.0 points)
Chapter 12, Problem 36

The machine shop owner is considering hiring a military consultant. By talking to other machine shop owners and obtaining past data, the owner has estimated the military consultant was correctly issued a favorable report where a contract was later award 70% of the time, P(f | c) = 0.70. Also, the military consultant correctly issued an unfavorable report where no contract was awarded 80% of the time, P(u | n) = 0.80. Using decision tree analysis, compute the maximum fee the owner should pay the consultant for his services.

(For this problem, you will need to determine the expected value from problem 15. The answer is the drill press with EV=$11,200, but you are encouraged to confirm this on your own. )

a) $5,280
b) $7,820
c) $16,480
d) $25,200

Answer: _____

Note: Problem 15 below...
15. A machine shop owner is attempting to decide whether to purchase a new drill press, a lathe, or a grinder. The return from each will be determined by whether the company succeeds in getting a government military contract. The profit or loss from each purchase and the probabilities associated with each contract outcome are shown in the following payoff table. Compute the expected value for each purchase and select the best one.

A sample of n=100 scores is selected from a population with u= 80 with o= 20. on average how much error is expected between the sample mean and the population mean?
* 0.8 points
* 4 points
* 0.2 points
* 2 points
If random samples, each with n=4 scores, are selected from a normal population with u= 80 and o=36, what i

Attached is a Adobe pdf file. I am studying for a test and wish to use this problem as a guide. Please give as much detail as possible so that I may understand the concept.

A large number of simple random samples of size n = 85 are obtained from a large population of birth weights having a mean of 3420 g and a standard deviation of 495 g. The sample mean is calculated for each sample.
A) What is the approximate shape of the distribution of the sample means?
B) Determine the expected mean and the

For a population with u=80 and o=20, the distribution of sample means based on n=16 will have expectedvalue of _____ and a standard error of ____.
* 80; 1.25 (this is the one i had chosen at 1st?)
* 80; 5
* 5; 80
* 20; 20
Samples of n=16 scores are selected from a population. If the distribution of sample means has an e

For a sample selected from a population with a mean of u=50 and a standard deviation of o=10: what is the expectedvalue of M and the Standard error of M for a sample of n=4 scores?

I need help finishing this matrix. This is my assignment below
1. identify the type and size of the sample population appropriate for each research methodology listed in the matrix
2. describe the data collection instruments and techniques appropriate for each research methodology listed in the matrix; be sure to check that t

Information from the American Institute of Insurance indicates the mean amount of life insurance per household in the United States is $110,000. This distribution is positively skewed. The standard deviation of the population is not known.
A. a random sample of 50 household revealed a mean of $112,000 and a standard deviation

One sample has n = 8 scores with SS = 45 and the second sample has n = 4 scores with SS = 15.
In another set, one sample has n = 8 scores with SS = 150 and the second sample n = 4 scores with SS = 90.
How to calculate expected difference between the samples means, and how does larger variability affect the size of the stan
