Test the claim that the mean GPA of Orange Coast students is larger than the mean GPA of Coastline students at the 0.10 significance level. The null and alternative hypothesis would be: Ho: H0 < µc Họ:po < Pc Ho:µ0 = µc_Ho: Po = Pc Ho:µo 2 µc_Ho:po 2 PC H1: µ0 > µc H1:po > pc H1:40 € µc H1:Po + pc H1:µo < µc_H1:po < PC

Test the claim that the mean GPA of Orange Coast students is larger than the mean GPA of Coastline
students at the 0.10 significance level.
The null and alternative hypothesis would be:
Но: ро < нс Но: ро < Рс Но: мо — нс Но:ро — рс Но: по > нс Но: ро > PC
H1: µ0 > µc H1:po > Pc H1:40 + µc H1:po + pc H1:µ0 < µc_H1:po < PC
The test is:
left-tailed right-tailed two-tailed
The sample consisted of 35 Orange Coast students, with a sample mean GPA of 3 and a standard deviation
of 0.04, and 35 Coastline students, with a sample mean GPA of 2.97 and a standard deviation of 0.05.
The test statistic is:
(to 2 decimals)
The p-value is:
(to 2 decimals)
Based on this we:
O Reject the null hypothesis
O Fail to reject the null hypothesis
