Suppose that the population of the scores of all high school seniors who took the SAT-V (SAT verbal) test this year follows a Normal distribution with mean μ = 480 and standard deviation σ = 90. A report claims that 10,000 students who took part in a national program for improving one's SAT-V score had significantly better scores (at the 0.05 level of significance) than the population as a whole. In order to determine whether the improvement is of practical significance, one should find out the actual mean score of the 10,000 students and find out the actual P-value. Use a two-sided test rather than the one-sided test implied by the report.
