Test the claim that the mean GPA of night students is smaller than 3.2 at the 0.10 significance level.

Question
Test the claim that the mean GPA of night students is smaller than 3.2 at the 0.10 significance level.
The null and alternative hypothesis would be:
`H_0: mu ge 3.2`
`H_1: mu < 3.2`
`H_1: mu < 3.2`
`H_0: mu = 3.2`
`H_1: mu ≠ 3.2`
`H_1: mu ≠ 3.2`
`H_0: p = 0.8`
`H_1: p ≠ 0.8`
`H_1: p ≠ 0.8`
`H_0: p ge 0.8`
`H_1: p < 0.8`
`H_1: p < 0.8`
`H_0: p le 0.8`
`H_1: p > 0.8`
`H_1: p > 0.8`
`H_0: mu le 3.2`
`H_1: mu > 3.2`
`H_1: mu > 3.2`
The test is:
left-tailed
two-tailed
right-tailed
Based on a sample of 55 people, the sample mean GPA was 3.15 with a standard deviation of 0.05
The p-value is: (to 2 decimals)
Based on this we:
- Reject the null hypothesis
- Fail to reject the null hypothesis
