a. A statistics practitioner wants to test the following hypotheses: H0: p = .70 H1: p > .70 A random sample of 100 produced p^ = .73. Calculate the p-value of the test. b. Repeat part (a) with p^ = .72. c. Repeat part (a) with p^ = .71. d. Describe the effect on the z-statistic and its p-value of decreasing the sample proportion.
