Test the claim that the mean GPA of night students is significantly different than 2.7 at the 0.01 significance level.

The null and alternative hypothesis would be:

H0:p0.675H0:p0.675

H1:p>0.675H1:p>0.675

H0:=2.7H0:=2.7

H1:2.7H1:2.7

H0:p0.675H0:p0.675

H1:p<0.675H1:p<0.675

H0:p=0.675H0:p=0.675

H1:p0.675H1:p0.675

H0:2.7H0:2.7

H1:<2.7H1:<2.7

H0:2.7H0:2.7

H1:>2.7H1:>2.7

The test is:

right-tailed

two-tailed

left-tailed

Based on a sample of 80 people, the sample mean GPA was 2.75 with a standard deviation of 0.06

The p-value is:_______(to 2 decimals)

Based on this we:

• Reject the null hypothesis
• Fail to reject the null hypothesis
