6. In the HSB data set, compare the standardized reading scores to the standardized math scores, i.e., test the null hypothesis that there is no difference between students' reading and math abilities. (use a = .01). Specify the null and alternative hypotheses, and report the values of Ya, sa, the standard error of the mean difference, the sample size n, the value of the test statistic, t, and the p-value associated with this value of t. Clearly state your decision regarding the null hypothesis and your conclusion in the context of the problem. Write down the 95% confidence interval for M1 - M2 and interpret this interval.
