Test the claim that the mean GPA of night students is significantly different than 2 at the 0.05 significance level.

The null and alternative hypothesis would be:

 

H0:p≥0.5 H1:p<0.5
 
H0:p≤0.5 H1:p>0.5
 
H0:μ≤2 H1:μ>2
 
H0:p=0.5 H1:p≠0.5
 
H0:μ≥2 H1:μ<2
 
H0:μ=2 H1:μ≠2
 



The test is:

 

left-tailed
right-tailed
two-tailed



Based on a sample of 30 people, the sample mean GPA was 2.05 with a standard deviation of 0.07

The test statistic is: (to 2 decimals)

The p-value is: (to 2 decimals)

Based on this we:

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