Question

(a) how many bottling plants had from 11 to 17 work stoppages? (b) how many bottling plants had 18 or more work stoppages? (c) what is the class width?

Explanation:

Step1: Analyze the bar graph for part (a)

Each bar represents the number of bottling plants in a particular range. The height of the bar for the range 11 - 17 is 1.

Step2: Analyze the bar graph for part (b)

For 18 or more, we consider the ranges 18 - 24, 25 - 31, 32 - 38. Each of their bars has a height of 1. So, \(1 + 1+1=3\).

Step3: Calculate class width for part (c)

Class width is the difference between the upper and lower - class limits. For the class 4 - 10, \(10 - 4=6\).

Answer:

(a) 1
(b) 3
(c) 6
