From the given data;
Draw the histogram of the given data as follows:
(b)
The measures of center and variation that best describe the data.
(b)
Answer to Problem 9E
Use the median to describe the center and five-number summary to describe the variation.
Explanation of Solution
Given:
The given data is:
Calculation:
The histogram of the given data as follows:
The tail of the graph extends to the right. Most of the data is on the left. Hence, the distribution is skewed right.
Therefore, use the median to describe the center and five-number summary to describe the variation.
(c)
The interpretation of the data.
(c)
Answer to Problem 9E
Most people withdraw less than $150 and hence, were charged a bank fee.
Explanation of Solution
Given:
The given data is:
