10.57 Let us now investigate the effects of another home condition: does the student have access to the Internet at home? Using a random sample of 500 observations from the PISA database, to be found in the data file PISA Sample, analyze the difference in means of the mathematics and reading scores of students who have Internet access at home and those who do not. In the file, 1 for Link_to_Internet indicates the presence of Internet access, while 2 indicates its absence. Also investigate if access to the Internet among male students makes a difference. Do the same for female students. Assume normality.
