Determine the critical values that would be used in testing each of the following null hypotheses using the classical approach. (Give your answers correct to three decim places.) (a) Ho: p = 0 vs. Ha: p + 0, with n = 18 and a = 0.05 -2.110 X (smaller value) (larger value) (b) Ho: p = 0 vs. Ha: p > 0, with n = 32 and a = 0.01 (c) Ho: p = 0 vs. Ha: p < 0, with n = 16 and a = 0.05
