Test the claim that the mean GPA of night students is significantly different than 3 at the 0.05 significance level.

The null and alternative hypothesis would be:

 

H0:μ≥3


H1:μ<3

 
H0:μ≤3


H1:μ>3

 
H0:p≥0.75


H1:p<0.75

 
H0:p≤0.75


H1:p>0.75

 
H0:μ=3


H1:μ≠3

 
H0:p=0.75


H1:p≠0.75

 



The test is:

 

right-tailed
two-tailed
left-tailed



Based on a sample of 60 people, the sample mean GPA was 3.03 with a standard deviation of 0.08

The p-value is: (to 2 decimals)

Based on this we:

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