Reports indicate that graduating students from a local high school have a mean English reading score of 51.8 with a standard deviation of 10.1. As an instructor in a rival school you are interested in seeing how your students compare. A random sample of 48 students from your program produces a mean score of 54.8 on the same test. Assume the standard deviation for your students is the same as for those in the other school. You want to test the hypothesis that the average test scores at your school are different from those in the other school. a) Calculate the appropriate test statistic for your sample. b) Give the absolute value of the critical values for a 5% significance level test of your hypothesis. c) Should you reject or keep the null hypothesis in this test? Answer 0 to keep it and 1 to reject it.
