What is your subjective probability that the New York Yankees will win next year’s World Series? What does that have to do with power?
Answer to relevant QuestionsIf σ = 15, n = 25, and we are testing H0: µ = 100 versus H1: µ > 100, what value of the mean under H1 would result in power being equal to the probability of a Type II error? This is most easily solved by sketching the ...In Exercise 15.3 what sample sizes would be needed to raise power to 0.70, 0.80, and 0.90? Calculate d^ for the comparisons you made in Exercise 16.10 and interpret the meaning of each. Calculate d^ for the comparison of WL with SIT in Exercise 16.18 using the standard deviation of the Control group to standardize the difference. Now we will expand on the analysis of Exercise 16.2. (a) Run a one-way analysis of variance on treatments 1 and 3 combined (n 5 20) versus treatments 2 and 4 combined. What question are you answering? (b) Why might your ...
