For Division | athletes the NCAA uses a sliding scale, based on both core GPA and the combined Mathematics and Critical Reading SAT score, to determine eligibility to compete in the first year of college. For athletes with a core GPA of 3.0, a score of at least 620 on the combined Mathematics and Critical Reading sections of the SAT exam is required. In 2011, the combined scores of the millions of college-bound seniors taking the SATs were approximately Normal with mean 1012 and standard deviation approximately 213. [x] % of all SAT scores of college-bound seniors are less than 620. Enter your answer as a percentage rounded to the nearest hundredth of a percent. 3.29 QUESTION 6 Exercise 13.24 The average performance of women on the SAT, especially the math part, is lower than that of men. The reasons for this gender gap are controversial. In 2011, college-bound senior women's scores on the SAT Math test followed a Normal distribution with mean 500 and standard deviation 113. The mean for men was 531. [x]% of women scored higher than the male mean.

QUESTION 4 Exercise 13.14 The WechslerAdult Intelligence Scale (WAIS) is an IQ test. Scores on the WAIS for the 20 to 34 age group are approximately Normally distributed with mean 110 and standard deviation 15. Scores for the 60 to 64 age group are approximately Normally distributed with mean 90 and standard deviation 15. Sarah, who is 30, scores 130 on the WAIS. Her mother, who is 60, takes the test and scores 105. Express both scores as standard scores, rounded to the nearest tenth, that show where each woman stands within her own age group. The standard score for Sarah is . The standard score for Sarah's mother is scored higher relative to her age group.
