Use the normal distribution of SAT critical reading scores for which the mean is 515 and the standard deviation is 118. Assume the variable x is normally distributed. (a) What percent of the SAT verbal scores are less than 650? (b) If 1000 SAT verbal scores are randomly selected, about how many would you expect to be greater than 550? (a) Approximately% of the SAT verbal scores are less than 650. (Round to two decimal places as needed.) (b) You would expect that approximately SAT verbal scores would be greater than 550. (Round to the nearest whole number as needed.)

The graph illustrates the distribution of test scores taken by College Algebra students. The maximum possible score on the test was 130, while the mean score was 71 and the standard deviation was 13. 32 45 97 110 58 71 84 Distribution of Test Scores Q What is the approximate percentage of students who scored less than 45 on the test? What is the approximate percentage of students who scored between 71 and 84 on the test? What is the approximate percentage students who scored between 58 and 84 on the test? What is the approximate percentage of students who scored between 45 and 97 on the test?

Suppose the scores on your last Algebra 2 test were normally distributed, with a mean of 81% and a standard deviation of 3%. To show you how you compared to your classmates, the teacher did not record your grades as per- centages, instead, she wrote them as z-scores. You look at your paper and see "2.66" written at the top. What was your score as a percentage? Explain how you determined your answer.

A successful basketball player has a height of 6 feet 11 ​inches, or 211 cm. Based on statistics from a data​ set, his height converts to the z score of 5.17. How many standard deviations is his height above the​ mean?
