Answer to Question #51194 in Statistics and Probability for Kaitlyn

Question

Answer the following questions:

a. State the decision rule based on p-values for a two-sided hypothesis test at level α = 0.01.


b. Consider the following hypothesis test where (n = 100).

H0: µ = 50 α = 0.10
Ha: µ > 50

Suppose z = -2.20. Compute the p-value. Should H0 be rejected?



c. Consider the following hypothesis test where (n = 100).

H0: µ = 50 α = 0.05
Ha: µ < 50

Suppose z = -2.20. Compute the p-value. Should H0 be rejected?



d. Consider the following hypothesis test where (n = 100).

H0: µ = 50 α = 0.01
Ha: µ ≠ 50

Suppose z = -2.20. Compute the p-value. Should H0 be rejected?
