Construction of a Type of Mean interval : Who Gets Paid More?

APSTAT-LIMEEK

You have probably heard that men are typically paid more than women for the same type of job. A researcher wanted to investigate this claim. Using information from a census, the researcher randomly selected $10$ occupations and looked at the median salary (in dollars) for men and women from each occupation. The median salaries per occupation and the differences (man-woman) are given in the table below. Each occupation is listed as a letter.
