1.) Test the claim that the mean GPA of night students islarger than the mean GPA of day students at the 0.10 significancelevel.The null and alternative hypothesis would be:
H0:μN≤μDH1:μN>μD
H0:μN=μDH1:μN≠μD
H0:pN≥pDH1:pN<pD
H0:pN=pDH1:pN≠pD
H0:μN≥μDH1:μN<μD
H0:pN≤pDH1:pN>pD
The test is:
right-tailed
two-tailed
left-tailed
The sample consisted of 30 night students, with a sample mean GPAof 2.7 and a standard deviation of 0.05, and 30 day students, witha sample mean GPA of 2.66 and a standard deviation of 0.04.The test statistic is: (to 2 decimals)The p-value is: (to 2 decimals)Based on this we:
