Question

Find the critical value for the indicated hypothesis test, then use this value and the provided information to make a conclusion about the null hypothesis (i.e., reject or fail to reject the null hypothesis).

1.The test statistic in a left-tailed test is z = −2.05; significance level α = 8%

2. Test at the significance level α = 5% the hypothesis H₀: p ≤ 0.04, given that the test statistic is z = 1.82.

3. Test at the significance level α = 1% the hypothesis H₀: p = 3.83, given that the test statistic is z = 2.41.
