Question

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:

College A: 3.7, 3.2, 3.0, 2.5, 2.7, 3.6, 2.8, 3.4
College B: 3.8, 2.8, 3.2, 4.0, 3.0, 3.6, 3.9, 2.6, 3.8, 4.0, 2.5, 3.6, 3.9
Construct a 95

Answer 1

Students' GPAs from two different colleges are compared using a 95% confidence interval to determine if there is a significant difference between their averages.

Step-by-step explanation:

The students at two different colleges are having their GPAs compared. There are 8 students from College A and 13 students from College B. The first step is to calculate the mean (average) GPA for each college, then using that data, construct a 95% confidence interval to see if there is a significant difference between the GPAs of the two colleges. Unfortunately, the question seems to be cut off before specifying what statistical method or confidence interval to construct. However, considering we have the GPAs for the students in two independent samples, we could use the formula for a confidence interval for two independent means to determine if there is a significant difference in averages.
