1. To test the null hypothesis p = 190 with a single sample of size n, we require that n at p0 t (l pa) 2 10. Our test statistic TS is P P0 app291 where 1\") is the sample proportion. (a) For a twotailed test, we may compute iza/z = i1nvNorm(a/2, 0, l) and check that the test-statistic falls in a tail. Or we may instead compute P = 2 I normalcdlTSL 00.0,1) and check that P 0.35 ? ii. What would we conclude if we rejected the null hypothesis with a two-tailed test? iii. Can we reject the null hypothesis at level of signicance 0: = 0.05, using a two-tailed test? iv. Can we reject the null hypothesis at level of signicance 0 = 0.01, using a two-tailed test
