Show work and formula please I only need the test statistic and p-value
Test the claim that the mean GPA of night students is smaller than the mean GPA of day students at the 0.10 significance level.
The null and alternative hypothesis would be:
H0:pN≤pDH0:pN≤pD
H1:pN>pDH1:pN>pD
H1:pN>pDH1:pN>pD
H0:μN≥μDH0:μN≥μD
H1:μN<μDH1:μN<μD
H1:μN<μDH1:μN<μD
H0:pN=pDH0:pN=pD
H1:pN≠pDH1:pN≠pD
H1:pN≠pDH1:pN≠pD
H0:μN≤μDH0:μN≤μD
H1:μN>μDH1:μN>μD
H1:μN>μDH1:μN>μD
H0:μN=μDH0:μN=μD
H1:μN≠μDH1:μN≠μD
H1:μN≠μDH1:μN≠μD
H0:pN≥pDH0:pN≥pD
H1:pN<pDH1:pN<pD
CorrectH1:pN<pDH1:pN<pD
The test is:
right-tailed
left-tailed
two-tailed
Correct
The sample consisted of 30 night students, with a sample mean GPA of 3.2 and a standard deviation of 0.06, and 30 day students, with a sample mean GPA of 3.24 and a standard deviation of 0.07.
The test statistic is: (to 2 decimals)
Use the conservative degree of freedoms.
The p-value is: (to 2 decimals)
