Question

According to the National Center for Education Statistics, 88% of elementary, middle-school, and secondaryschool students from families earning $75,000 or more per year use a computer at school, compared to 81% from families earning less than $20,000. Using a one-tail test at the 0.01 level, and assuming that the percentages are from independent samples of 500 families each, is the percentage of more-affluent students using computers at school significantly greater than for those from lower-income families? Determine and interpret the p-value for the test.
