Essay

State what the given confidence interval suggests about the two population means.
-A researcher was interested in comparing the GPAs of students at two different colleges. Independent simple
random samples of 8 students from college A and 13 students from college B yielded the following GPAs. Use a 0.10 significance level to test the claim that the mean GPA of students at college A is equal to the mean
GPA of students at college B. Use the traditional method of hypothesis testing. $$\text { (Note: } \left. \bar { x } _ { 1 } = 3.1125 , \bar { x } _ { 2 } = 3.4385 , \mathrm {~s} _ { 1 } = 0.4357 , \mathrm {~s} _ { 2 } = 0.5485 . \right)$$
