The following information was found regarding standardized tests used for college admitance. Scores on the SAT test are normally distributed with a mean of 984 and a standard deviation of 202. Scores on the ACT test are normally distributed with a mean of 20.9 and a standard deviation of 3.9. It is assumed that the two tests measure the same aptitude, but use different scales.\r
