Ten college students were randomly selected. Their grade point averages (GPAs) when they entered the program were between 3.5 and 4.0. The students' GPAs on entering the program (x) and their current GPAs (y) were recorded. The regression analysis is given below. Use the analysis to find a 95% confidence interval for the true slope.
The regression equation is y=3.584756+0.090953x with R-sq=0.001849 and 10-2=8 degrees of freedom
