The national average for cumulative sat score was 1026 in 2003 and the sd was 105. sat scores generally follow the normal curve pretty closely. i take a srs of 5 students from our stat 21 class and find that the average and sd in my sample are 1240 and 90. do you believe that the class average is more than the 2003 national average? if appropriate, do a hypothesis test to answer this question, including null and alternative hypotheses, a box model, test statistic, p-value, and interpret the p-value. if it is not appropriate to do a hypothesis test, explain why not.
