The mean SAT score in mathematics 572. A special preparation course claims that its graduates will score higher, on average, than the mean score 572. A random sample of 36 students completed the course, and their mean SAT score in mathema�cs was 584 with standard deviation of 32 a. At the 0.01 level of significance, State the null and alternate hypotheses, can we conclude that the preparation course does what it claims? Interpret the results. b. Construct 98% confidence interval. Does your confidence interval support the claim in your null hypothesis in part a
