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) Ho: A = . 65 versus Hj: * > . 65, a = . 05, x = 60, n = 81 (b) Ho: A = .30 versus Hj: A * .30, a = .05, x = 19, n = 35 (c) Ho: # 2 . 10 versus Hj : #
