For a sample of 48 finance majors, the average time spent reading each issue of the campus newspaper is 19.7 minutes, with a standard deviation of 7.3 minutes. The corresponding figures for a sample of 40 management information systems majors are 16.3 and 4.1 minutes. Using the 0.01 level of significance, test the null hypoth- esis that the population means are equal. Using the appro- priate statistical table, what is the approximate p-value for this test? Construct and interpret the 99% confidence interval for the difference between the population means.
