Question 473372: At a large company, the majority of the employees earn from $20,000 to $30,000 per year. Middle management employees earn between $30,000 and $50,000 per year while top management earn between $50,000 and $100,000 per year. A histogram of all salaries would have which of the following shapes?
A) Symmetrical
B) Uniform
C) Skewed to right
D) Skewed to left
I THINK the answer is A, but I can't get the add-ins for Excel to load on my mac. If I just do a "normal" bar graph, assuming that the majority of earners are in the 20k-29,999 range, then next highest number of earners are in the 30k to 49,000 range while the fewest number of earners are in the 50k+ range, then I would get a J, but that's not an option, and the skewed to left - there's no tail ... so this one is confusing me.

You can put this solution on YOUR website! Sketch the histogram.
You've got a pile of people between 10 and 30
Much fewer between 30 and 50
Very, Very few from 50 to 100
Notice how the distribution is tailing off to the right.

Ans: skewed right
