Question 1.121

1.121 Identify the histograms.

A survey of a large college class asked the following questions:

  1. Are you female or male? (In the data, male = 0, female = 1.)
  2. Are you right-handed or left-handed? (In the data, right = 0, left = 1.)
  3. What is your height in inches?
  4. How many minutes do you study on a typical week night?

Figure 1.35 shows histograms of the student responses, in scrambled order and without scale markings. Which histogram goes with each variable? Explain your reasoning.

1-c—currently there are more females in college than males. 2-b—there should be more righthanded students than left-handed. 3-d—height should be Normally distributed. 4-a—should be right-skewed, because some students will study much more than others.
