Explanation:

Step1: Identify class - width formula

Class width is calculated as the difference between consecutive lower - class limits.

Step2: Observe lower - class limits

The lower - class limits from the histogram are 160, 165, 170, 175, 180, 185.

Step3: Calculate class width

Take two consecutive lower - class limits, say 165 and 160. Class width = 165 - 160=5.
