Question

Question;Harvard University has recently revolutionized its financial aid policies, aimed at easing the financial strain on middle and upper-middle income families (Newsweek, August 18?25, 2008). The expected contribution of students who are admitted to Harvard has been greatly reduced. Many other elite private colleges are following suit to compete for top students. The motivation for these policy changes stems from the competition from public universities as well as political pressure.A spokesman from an elite college claims that elite colleges have been very responsive to financial hardships faced by families due to rising costs of education. Now, he says, families with income of \$40,000 will have to spend less than \$6,500 to send their children to prestigious colleges. Similarly, families with incomes of \$80,000 and \$120,000 will have to spend less than \$20,000 and \$35,000, respectively, for their children's education.Although in general, the cost of attendance has gone down at each family-income level, it still varies by thousands of dollars amongst prestigious schools. The accompanying table shows information on the cost of attendance by family income for 10 prestigious schools.

Determine whether families with income of \$40,000 will have to spend less than \$6,500 to send their children to prestigious colleges. (Use? = 0.05.)2. Repeat the hypothesis test from part 1 by testing the spokesman's claims concerning college costs for families with incomes of \$80,000 and \$120,000, respectively. (Use? = 0.05.)3. Assess the validity of the spokesman's claims.
