Compute: The mean of the difference scores, the sum of squares, the estimated population variance of difference scores, the variance of the distribution of means of difference scores and the standard deviation of the distribution of means of difference scores Problem 1: A teacher at the University of Alabama wants to know if going to tutoring is helping his math students. He predicts that going to tutoring will increase student’s test scores. To test this hypothesis (α = .05), he...
