Question

based on the histogram above, what is the class width? class width = what is the sample size? sample size = question help: message instructor

Explanation:

Step1: Find class - width

Class - width is the difference between consecutive lower - class limits. For example, the lower - class limits are 1, 3, 5, etc. So, $3 - 1=2$.

Step2: Calculate sample size

Sample size is the sum of all frequencies. The frequencies are 10, 2, 6, 8, 4, 2. So, $10 + 2+6 + 8+4 + 2=32$.

Answer:

Class width = 2
Sample size = 32
