1. use the following data for questions #10 - #15

34, 34, 65, 33, 35, 54, 57, 48, 42, 33, 36, 38, 44, 35, 36, 32, 36, 37, 44, 45
create a dotplot with intervals of size 5. what is the shape of the dotplot?
a. left skewed
b. right skewed
c. uniform
d. approximately normal

Explanation:

Step1: Analyze the distribution of license - getting ages

Most people get their license when young, but some get it much later. This means there is a tail on the right side of the distribution (since the "later" ages are larger values).

Step2: Recall the shape definitions

A skewed - right distribution has a longer tail on the right. A skewed - left distribution has a longer tail on the left. A normal distribution is symmetric. A bimodal distribution has two peaks. A uniform distribution has approximately equal frequencies across intervals.

Answer:

A. skewed right
