13 9-0?! 14 9-0?! 15 9-0?! Given a = 0.05, the critical value for the testis, 2.363 1.983 1.660 1.290 The approximate p-value for the testis, 0.072 0.063 0.038 0.023 Based on the p-value in the previous question, Do not reject H0 at o = 0.10; do not reject H0 at o = 0.05 Reject H0 at o = 0.10; reject H0 at o = 0.05 Reject H0 at o = 0.10; do not reject H0 at o = 0.05 Do not reject H0 at o = 0.10; reject H0 at o = 0.05 Decision rule: Reject Ho ifp-value is
