In 2005, 1,475,623 students heading to college took the SAT. The distribution of scores in the math section of the SAT follows a normal distribution with mean u = 520 and standard deviation o = 115.
O Part (a)
O Part (b)
O Part (c)
For 2012, the SAT math test had a mean of 514 and standard deviation 117. The ACT math test is an alternate to the SAT and is approximately normally distributed with mean 21 and standard deviation 5.3. If one person took the SAT math test and scored 700 and a second person took the
ACT math test and scored 34, who did better with respect to the test they took? (Round your answers to two decimal places.)
The z-score for an SAT score of 700 is
The z-score for an ACT score of 34 is
Therefore, the student who took the --Select--- v did better, because that person has a --Select-- v z-score.
