Let's take a look at the given frequency table. This table has 4 intervals of 20 minutes each. Looking at the table, we can see that there are 5 values in the first interval, 9 values in the second interval, 12 values in the third interval, and 3 values in the fourth interval.

Now, let's display our data in a histogram. We will draw a bar for each interval that we used in the frequency table and make the height of each bar equal to the frequency of the interval. Keep in mind that the bars should touch but not overlap. Do not forget to label the axes!
