The study in Exercise 9 actually measured the bicep circumference in centimeters. The dot plot in Exercise 9 was formed by dividing each measurement by 2.54 to convert it to inches. Here is the dot plot of the original values in cm. Do the two dot plots look different? What might account for that?

Data From Exercise 9

A study of body fat on 250 men collected measurements of 12 body parts as well as the percentage of body fat that the men carried. Here is a dotplot of their bicep circumferences (in inches). What does the dotplot say about the distribution of the size of men’s biceps?

# of Men 100 80 60 40 20 10 12 Bicep Size (in.) 14 16
