    Question #1. The first step is to arrange the data in ascending order from left to right. Have you done that?

    They are arranged in descending order, but that will do. Now can you complete the histogram.|dw:1438629854648:dw|

    The height of the first bar was found by counting the number of data values that are in the interval 20 to 29. The values 21, 21, 23, 25, 27 fall in the interval, giving a total of 5 values.

    Correct. There are 2 values in that interval, so we can draw the bar as follows: |dw:1438630795612:dw| Can you do the remaining two intervals?

    Number of values in the interval 40 to 49 = ? Number of values in the interval 50 to 59 = ?
