The following hypothesis-testing situation is given:

H0: π ≤ .50 and H1: π > .50. The

significance level is .10, and the sample size is 12.

a. What is the decision rule?

b. There were nine successes. What is your decision regarding the null hypothesis? Explain.

Definition Definition Number of subjects or observations included in a study. A large sample size typically provides more reliable results and better representation of the population. As sample size and width of confidence interval are inversely related, if the sample size is increased, the width of the confidence interval decreases.
