Question

A college graduate seeks a job as an executive assistant and collects data on starting salaries from 200 companies: 100 private and 100 public. The data are summarized in the cumulative relative frequency histograms below. Using the histograms, what is a correct comparison of public and private starting salaries?

a) Both salary distributions are skewed left.
b) In both groups, more than 10 percent of salaries are greater than $55,000.
c) The median salary for both groups is between $45,000 and $50,000.
d) Both private and public salaries range from a low of $35,000 to $40,000 to a high of $60,000 to $65,000.

Answer 1

The median salary for both public and private starting salaries is between $45,000 and $50,000.

Step-by-step explanation:

The correct comparison of public and private starting salaries can be determined by analyzing the cumulative relative frequency histograms. Based on the histograms, we can conclude that option c) The median salary for both groups is between $45,000 and $50,000 is correct. This is because the median represents the middle value, and in both private and public groups, the median salary falls within the range of $45,000 to $50,000.
