We wish to estimate the difference in mean GPAS at two different colleges. Consider the following sample statistics: School A records the follwoing sample statistics: ā=4.05, =0.03, n=80. School B records the follwoing sample statistics: =3.95, s, =0.04, ng=90. We wish to build a 95 % cofidence interval to estimate the difference in mean GPAS between these schools.

Question
We wish to estimate the difference in mean GPAS at two different colleges. Consider the following sample statistics: School A records the follwoing sample statistics: =4.05, s. =0.03, n=80. School B records the follwoing sample statistics: ē=3.95, s. =0.04, nz=90. We wish to build a 95 % cofidence interval to estimate the difference in mean GPAS between these schools. Define your variable: Let u the mean GPA that School A was higher than School B. Let p be the proprotion School A students that have a higher GPA than School B. O Let u be the mean GPA. O Let u be the mean GPA at School A. Create and interpret a 95% Confidence Interval. Round your answers to one decimal place. and Select an answer Select an answer What is the margin of error? Round your answer to one decimal place. Do these results suggest that School A might hanve higher means on this test? ? Do these results PROVE that School A might hanve higher means on this test? ? The campus president at School A made the following statement. "Our students have an average GPA of 0.15 points higher that students at School B.". What do you think of this claim? Select an answer
