Concept explainers
(a)
To explain the shape of the given dot plot.
(a)

Answer to Problem 22E
Right skewed.
Explanation of Solution
Given:
Based on the given dot plot it is clearly seen that the shape of the given distribution is positively skewed or right skewed. As it seems the tail of the distribution is towards the right side. Also the value of
(b)
To identify the mean and median of the distribution of distance.
(b)

Answer to Problem 22E
Mean = 67 inch.
Median = 66 inch.
Explanation of Solution
Based on the given statistics about the distance data, the mean is equal to 67 inch and the median is equal to 66 inch.
(c)
To identify the standard deviation and the
(c)

Answer to Problem 22E
Standard deviation = 4.29
Interquartile
Explanation of Solution
Based on the given statistics about the data the standard deviation is 4.29 inch. and the Interquartile range is the difference between the third and the first
