You want to examine the effectiveness of a new tutoring program at SWC. A sample of n=9 stats students is used to evaluate t. Each students grade point average is recorded before the program and after the program. The average GPA improved by Mp=0.60 points with s^2 =0.09. the researcher would like to use the sample to estimate how much effect the workshop would have for the entire college population. Which of the following is the 80% confidence interval for these data? A.    μD=0.60 + 0.10(1.397) B.    μD=0.60 +  0.09(1.860) C.   μD=0.60  +  0.01(1.397) D.    μD =0.60 + 0.10(1.860)
