what is the sample size?
sample size =

Explanation:

Step1: Calculate class width

Class width is the difference between upper and lower boundaries of a class. For example, between \(1\) and \(3\), \(3 - 1=2\).

Sample size is the sum of all frequencies. \(10 + 6+7 + 2+3 + 5=33\)

Answer:

Class width = \(2\)
Sample size = \(33\)
