Consider Example 14 about the power of the test used in the TT experiment for testing H0: p = 0.50 against Ha: p > 0.50, where p is the probability of a correct prediction about which hand was nearer the researcher’s hand. In a significance test planned for a second set of trials, the power was reported as 0.98 at p = 2/3.
a. How should the probability of 0.98 be interpreted?
b. In context, what is a Type II error for this experiment?
c. What is the probability of committing a Type II error if p = 2/3?
