athletes per country
number of countries
1 - 20 21 - 40 41 - 60 61 - 80 81 - 100
number of athletes

Explanation:

Step1: Count data in intervals

For the interval 1 - 20, there are 2 values (6, 20), so the bar height for this interval is 2. For 21 - 40, there are 0 values. For 41 - 60, there are 2 values (44, 49), so the bar height is 2. For 61 - 80, there is 1 value (75), so the bar height is 1. For 81 - 100, there are 2 values (98, 100), so the bar height is 2.

Step2: Set bar - heights on histogram

Set the bar heights for the intervals 21 - 40, 41 - 60, 61 - 80, 81 - 100 to 0, 2, 1, 2 respectively.

Answer:

The bar heights for the intervals 21 - 40, 41 - 60, 61 - 80, 81 - 100 should be set to 0, 2, 1, 2 respectively.
