The three package designs are labeled A, B, and C. The consumers are classified according to age and package design preference.| A | B | C | Total | |
| Under 25 years | 22 | 34 | 40 | 96 |
| 25 or older | 54 | 28 | 22 | 104 |
| Total | 76 | 62 | 62 | 200 |
If one of these consumers is randomly selected and prefers design B, what is the probability that the person is 25 or older?
a) 0.28
b) 0.14
c) 0.45

Q:
Cindy Ho, VP of Finance at Discrete Components, Inc. (DCI), theorizes that the discount level offered to credit customers affects the average collection period on credit sales. Accordingly, she has designed an experiment to test her theory using four sales discount rates (0%, 2%, 4%, and 6%). First, she classified DCI's credit customers into three categories by total assets (small, medium, and large). Then, she randomly assigned four customers from each category to a sales discount rate. In Cindy's experiment "sales discount rate" is ________.
a) a surrogate variable
b) the dependent variable
