Question

based on the histogram above, what is the class width? class width = what is the sample size? sample size = check answer

Explanation:

Step1: Find class - width

The lower - class limits are 1, 3, 5, 7, 9, 11. Subtract consecutive lower - class limits. For example, \(3 - 1=2\). The class width is the difference between consecutive lower - class limits. So the class width \(w = 2\).

Step2: Calculate sample size

The sample size \(n\) is the sum of the frequencies. The frequencies are 8, 5, 10, 2, 3, 9. Then \(n=8 + 5+10 + 2+3+9=37\).

Answer:

Class width = 2
Sample size = 37
