56. B The hypothesis was not rejected at level alpha=.05.So p value was higher than 0.05 and so higher than 0.025 as well. So the test will again fail to reject the null hypothesis at level =0.025. 57. A The hypothesis was rejected at level=0.01.So, p value was less than 0.01 and so less than 0.10 as well.

Given that a researcher has the null hypothesis that μ=μ0 and alternative hypothesis that μ=μ1≠ μ0, and that the population variance is known as σ2. Also, he knows that he wants to reject the null hypothesis at a significance level of α which gives a corresponding Z score, called it Zα/2.
