c. centers: career b has greater median hourly earnings than career

d. spreads: the hourly earnings for career a are more spread out.

Explanation:

Step1: Analyze the centers (medians)

The median is the middle - value of a data set. Looking at the dot - plots, the values for Career A are generally higher. So, Career A has a greater median.

Step2: Analyze the spreads

The spread of a data set refers to how much the data is dispersed. Career A's data points are spread over a larger range of values (from approximately 35 to 85) compared to Career B's data points (from approximately 30 to 50). So, Career A's earnings are more spread out.

Answer:

B. Centers: Career A has greater median hourly earnings than career B.
D. Spreads: The hourly earnings for career A are more spread out.
