Question

PLEASE HELP

For a hypothesis test of H0: p = 0.35 against the alternative Ha: p > 0.35, the z test statistic is found to be 2.45. What can be said about this finding?


A. The finding is significant at α = 0.05, but not at α = 0.01.


B. The finding is significant at α = 0.01, but not at α = 0.05.


C. The finding is significant at both α = 0.05 and α = 0.01.


D. The finding is not significant at α = 0.05 and α = 0.01.

Answer 1

The finding is significant at both α = 0.05 and α = 0.01.

Answer 2

C

Explanation:

Is is a one-tailed test

P(z < 2.45) = 0.9929

1 - 0.9929 = 0.0071

Significant at both 0.05 and 0.01 because both are greater than 0.0071
