Calculate the test statistic and p-value for each sample. use appendix c-2 to calculate the p-value. (negative amount should be indicated by a minus sign. round your test statistic to 2 decimal places and p-value to 4 decimal places.)

test statistic p-value
(a) h0: p = .60 versus h1: p > .60, a = .05, x = 56, n = 80
(b) h0: p = .30 versus h1: p ? .30, a = .05, x = 18, n = 40
(c) h0: p = .10 versus h1: p < .10, a = .01, x = 3, n = 100
