Question

The z statistic for a one-sided test is z = 2.433 for an alternative Ha: μ > μa. This test is:

a. unable to determine

b. significant at α = 0.05 but not α = 0.01

c. not significant at both α = 0.05 and α = 0.01

d. significant at both α = 0.05 and α = 0.01

Answer 1

Answer #1

here for right tailed test statitic ; p value =0.0075

The one-sample t statistic from a sample of n = 21 observations for the two-sided test of H0: μ = 60, Ha: μ ≠ 60 has the value t = –1.98. Based on this information: we would reject the null hypothesis at α = 0.05. All of the answers are correct. 0.025 < P-value < 0.05. we would reject the null hypothesis at α = 0.10
