10.58 We will now understand the effects of another home condition: does the student have books at home to help with their school work? 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 books at home and those who do not. In the file, 1 for Books_to_help_school_work indicates the presence of books, while 2 indicates their absence.

Also investigate if the presence of books among male students makes a difference. Do the same for female students. Assume normality.
