Question

Alexandra kept track of her salary for 15 weeks and created the histogram below what does the gap for 21-30 tell Alexandra about her weekly salary??

Answer 1

I'm guessing the options are:

A. She did not work that week

B. Her salary was between 21 and 30 dollars

C. None of her paychecks were between 21 and 30 dollars

D. She only had 14 paychecks

The correct answer is C. None of her paychecks were between 21 and 30 dollars

Answer 2

This gap shows that there was never a week in which she made between 21 and 30 dollars. She always made more than 30 or less than 21.

We can tell this because a histogram shows the amount of times something fell within that data point. You can see the number 3 for 1-10, which means that she got a paycheck within that range 3 times.
