QUESTION 11

Math SAT Question 2

The scores of men on the math SAT follow a Normal distribution; so do those of women. Let µ1 (respectively, µ2) denote the average math SAT score of men (respectively, women).

A random sample of 20 men was selected. The average math SAT score of the men selected was 607.8 with a standard deviation of 48.76.

Another random sample of 23 women was selected (independently of the sample of men). The average math SAT score of the women selected was 542.71 with a standard deviation of 53.1.

Obtain a 94% confidence interval for µ1- µ2.

a. (34.8, 95.3)

b. (33.9, 96.2)

c. (35.0, 95.2)

d. (34.1, 96.4)

e. (35.3, 94.7)
