# Probability distribution for student survey

100 students in a statistics class were asked if they believed that all tests on the Monday following the football game win over their rival should be postponed automatically. The results were:

Strongly agree: 40

Agree: 30

Neutral: 20

Disagree: 10

Strongly disagree: 0

Numeric scale for each category is as follows:

Strongly agree = 5

Agree = 4

Neutral = 3

Disagree = 2

Strongly disagree = 1

a. Transform this into a numeric score, using the following random variable scale, and find a probability distribution for the results.

b. Let X = the numeric score. Compute the expected value of X.

c. Compute the variance and standard deviation for the random variable X.
