Test the claim that the mean GPA of night students is smaller than 2 at the 0.10 significance level.

The null and alternative hypothesis would be:

H0H0:?pσμsx̄p̂ ?=≠≥≤<> Select an answer20.04351.950.10

H1H1:?σsx̄μp̂p ?≠=<>≤≥ Select an answer0.040.101.95352

The test is:

right-tailed

two-tailed

left-tailed



Based on a sample of 35 people, the sample mean GPA was 1.95 with a standard deviation of 0.04

The p-value is: (to 4 decimals)

Based on this we:

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