Question

Consider a test of H0: μ=75 performed with the computer. The software reports atwo-tailed p-value of 0.1032.

Make the appropriate conclusion for each of the following situations.

a Ha:μ<75, z=−1.63,α=0.05

b. Ha:μ<75, z=1.631,α=0.07

c.Ha:μ>75, z=1.63, α=0.07

d. Ha:μ≠75, z=−1.63, α=0.01

a. Choose the correct answer below.

A) There is sufficient evidence to reject H0.

B) There is insufficient evidence to reject H0.

Answer #1

**1. Ha:μ<75, z=−1.63,α=0.05**

p value=0.0515 .P value >alpha.

B) There is insufficient evidence to reject H0.

**2. Ha:μ<75, z=1.631,α=0.07**

p value=0.0514 and **α=0.07 .**therefore p value
< alpha.

A) There is sufficient evidence to reject H0.

**3.Ha:μ>75, z=1.63, α=0.07**

p value=0.0515 and **α=0.07 .**therefore p value
< alpha.

A) There is sufficient evidence to reject H0.

**4. Ha:μ≠75, z=−1.63, α=0.01**

p value=0.1032 .P value >alpha.

B) There is insufficient evidence to reject H0.
