0/1 pt 3 19 Details
Test the claim that the mean GPA of night students is
larger than 2.7 at the .005 significance level.
The null and alternative hypothesis would be:
$H_0: \mu = 2.7$  $H_0: p = 0.675$  $H_0: \mu = 2.7$
$H_1: \mu > 2.7$  $H_1: p < 0.675$  $H_1: \mu < 2.7$
$H_0: p = 0.675$  $H_0: p = 0.675$  $H_0: \mu = 2.7$
$H_1: p \neq 0.675$  $H_1: p > 0.675$  $H_1: \mu \neq 2.7$
The test is:
right-tailed two-tailed left-tailed
Based on a sample of 25 people, the sample mean GPA
was 2.71 with a standard deviation of 0.03
The test statistic is:
(to
2 decimals)
The critical value is:
(to
2 decimals)
Based on this we:
Reject the null hypothesis
Fail to reject the null hypothesis

Question 21
0/1 pt 3 19 Details
Test the claim that the mean GPA of night students is
larger than 2.7 at the .005 significance level.
The null and alternative hypothesis would be:
H0: μ = 2.7 H0: p = 0.675 H0: μ = 2.7
H1: μ > 2.7 H1: p < 0.675 H1: μ < 2.7
H0: p = 0.675 H0: p = 0.675 H0: μ = 2.7
H1: p ≠ 0.675 H1: p > 0.675 H1: μ≠ 2.7
The test is:
right-tailed two-tailed left-tailed
Based on a sample of 25 people, the sample mean GPA
was 2.71 with a standard deviation of 0.03
The test statistic is:
(to
2 decimals)
The critical value is:
(to
2 decimals)
Based on this we:
Reject the null hypothesis
Fail to reject the null hypothesis
