31. The 2018 Math Portion of the SAT scores are normally distributed with a mean of 527 and a standard deviation of 117. Give the range of scores that will satisfy the 68%, 95% and 99.7% of the Empirical Rule.
32. Use the mean and standard deviation from #31 for the Math Portion of the SAT. Suzette took the SAT in 2018 and scored higher, on the Math Portion, than the bottom 30% but lower than the top 12% of those taking the test. Give the upper and lower bounds for Suzette’s score.

The SAT scores earned on the math portion are approximately
normally distributed with mean 516 and standard deviation 116.
Answer the following questions based on this information. Make sure
you show your work.
1. Using a printout of the graph above or making your own copy,
mark the mean SAT score on the math proportion at the appropriate
place. Then mark values of score that are 1, 2, and 3 standard
deviations away from the mean value. Labeling your marks...

Suppose that SAT math scores are normally distributed with a
mean of 516 and a standard deviation of 115, while ACT math scores
have a normal distribution with a mean of 22 and a standard
deviation of 5. James scored 650 on the SAT math and Jacob scored
29 on the ACT math. Who did better in terms of the standardized
z-score? Group of answer choices James Jacob They did relatively
the same. Impossible to tell because of the scaling

Math SAT scores are known to be normally distributed
with mean of
500 and standard deviation of 100. Answer the following questions.
(I also want to see
good notation and some of your calculations.)
a) Suppose we randomly select one person who has taken the SAT.
What is the
probability their math score is between 525 and 550?
b) Suppose we randomly select 25 people who have taken the SAT.
What is the
probability their average math score is between...

Math SAT scores (Y) are normally distributed with a
mean of 1500 and a standard deviation of 140. An evening school
advertises that it can improve students' scores by roughly a third
of a standard deviation, or 30 points, if they attend a course
which runs over several weeks. (A similar claim is made for
attending a verbal SAT course.) The statistician for a consumer
protection agency suspects that the courses are not effective. She
views the situation as follows:...

Scores for men on the verbal portion of the SAT test are
normally distributed with a mean of 509 and a standard deviation of
112. Randomly selected men are given the Columbia Review Course
before taking the SAT test. Assume the course has no effect.
a) If 1 of the men is randomly
selected, find the probability his score is at least 590
b) If 16 of the men are randomly
selected, find the probability that their mean score is...
