Calculate the test statistic and p-value for each sample. Use Appendix C-2 to calculate the p-value. (Negative values should be indicated by a minus sign. Round your test statistic to 3 decimal places and p-value to 4 decimal places.)
Test Statistic p-value
(a) H0: π ≤ .65 versus H1: π > .65, α = .05, x = 63, n = 84
(b) H0: π = .30 versus H1: π ≠ .30, α = .05, x = 16, n = 35
(c) H0: π ≥ .10 versus H1: π < .10, α = .01, x = 4, n = 116
