10.56 Let us now investigate another home condition:

can the student use educational software 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 between students who have access to educational software and those who do not. In the file, 1 for Educational_software indicates that the student can use educational software, while 2 indicates that the student cannot. Assume normality.
