(a)
To construct: the stem plot on the basis of given data.
(a)

Explanation of Solution
Given:
Graph:
By seeing the stem-leaf plot minimum and maximum values are 46 and 93 respectively so the spread of the data will be 46 to 93.
(b)
To construct: the histogram on the basis of given data and explain the shape, centre and spread of the distribution and about the outlier.
(b)

Explanation of Solution
Given:
Graph:
The representing the histogram looks symmetric because of centre in the middle and median would be around 70 to 75 while the minimum and maximum values are 45 and 98 respectively so the spread of the data would be between 45 and 48.
(c)
To Explain: that which plot is better a stem plot or histogram.
(c)

Answer to Problem 2.67RE
Histogram
Explanation of Solution
By seeing the both the plot, it is observed that pattern of both the plot is approximately similar but the pattern of histogram is better than stem plot because the stem plot lies in its favour compared to the histogram.
