Chapter 1.2, Problem 67E

To determine

To find: the histogram which suits the given questions

Answer to Problem 67E

Histogram (c) goes with question (i)

Histogram (d) goes with question (iv)

Histogram (b) goes with question (ii)

Histogram (a) goes with question (iii)

Explanation of Solution

Given:

(i)Female or male (In the data, male = 0, female = 1.)

(ii)Right-handed or left-handed (In the data, right = 0, left = 1.)

(iii)Height in inches

(iv)The study timeat weeknight

  

Histogram (a) goes with question (iii) i.e. it shows the distribution of height in inches as most of the respondents from a large high school class fall in same group and few of them have height more than normal.

Histogram (b) goes with question (ii) i.e. it shows if the student from a large high school class are right handed or left handed. Since right is 0 and left is 1, and generally people are right handed. Histogram (b) shows that maximum of them are right handed that goes with general tendency and very few are left handed.

Histogram (c) goes with question (i) i.e. it categorizes student from a large high school class on the basis of gender. As male = 0 and female = 1, there are more females than males in the class.

Histogram (d) goes with question (iv) i.e. haw much time does each student from a large high school class for studied typical weeknight. The distribution has variations that are possible due to variation in studying time. The distribution of the histogram is symmetric.
