Test the claim that the mean GPA of night students is smaller than 3.4 at the 0.005 significance level. The null and alternative hypothesis would be: H0:μ≤3.4H0:μ≤3.4 H1:μ>3.4H1:μ>3.4...

Test the claim that the mean GPA of night students is smaller than 3.4 at the 0.005 significance level.

The null and alternative hypothesis would be:

H0:μ≤3.4H0:μ≤3.4
H1:μ>3.4H1:μ>3.4

H0:p≤0.85H0:p≤0.85
H1:p>0.85H1:p>0.85

H0:p=0.85H0:p=0.85
H1:p≠0.85H1:p≠0.85

H0:p≥0.85H0:p≥0.85
H1:p<><>

H0:μ≥3.4H0:μ≥3.4

The test is:

right-tailed

two-tailed

left-tailed

Based on a sample of 80 people, the sample mean GPA was 3.38 with a standard deviation of 0.08

The p-value is: (to 2 decimals)

Based on this we:
