Chapter 21.3, Problem 8E

Consider a variation of the PDC decision tree shown in Figure 21.5. The company must first decide whether to undertake the market research study. If the market research study is conducted, the outcome will either be favorable (F) or unfavorable (U). Assume there are only two decision alternatives d1 and d2 and two states of nature s1 and s2. The payoff table showing profit is as follows:

  State of Nature
Decision Alternative s1 s2
d1 100 300
d2 400 200
  1. a. Show the decision tree.
  2. b. Use the following probabilities. What is the optimal decision strategy?
P(F) = .56 P(s1 | F) = .57 P(s1 | U) = .18 P(s1) = .40
P(U) = .44 P(s2 | F) = .43 P(s2 | U) = .82 P(s2) = .60

Suppose that you want to estimate the mean monthly gross income of all households in your local community. You decide to estimate this population parameter by calling 150 randomly selected residents and asking each individual to report the household’s monthly income. Assume that you use the local phone directory as the frame in selecting the households to be included in your sample.  What are some possible sources of error that might arise in your effort to estimate the population mean?
For the distribution shown, match the letter to the measure of central tendency. A B C C Drag each of the letters into the appropriate measure of central tendency. Mean C Median A Mode B
A physician who has a group of 38 female patients aged 18 to 24 on a special diet wishes to estimate the effect of the diet on total serum cholesterol. For this group, their average serum cholesterol is 188.4 (measured in mg/100mL). Suppose that the total serum cholesterol measurements are normally distributed with standard deviation of 40.7. (a) Find a 95% confidence interval of the mean serum cholesterol of patients on the special diet.
