Question

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:μN=μDH0:μN=μD
H1:μN≠μDH1:μN≠μD
H0:μN≥μDH0:μN≥μD
H1:μN<μDH1:μN<μD
H0:pN≥pDH0:pN≥pD
H1:pN<pDH1:pN<pD
H0:pN=pDH0:pN=pD
H1:pN≠pDH1:pN≠pD
H0:μN≤μDH0:μN≤μD
H1:μN>μDH1:μN>μD
H0:pN≤pDH0:pN≤pD
H1:pN>pDH1:pN>pD



The test is:

 

right-tailed
left-tailed
two-tailed
