Answer to Problem 92E
Median = 7.5
Explanation of Solution
Given:
The dot plot:
Formula used:
Calculation:
(b)
To compare the
(b)

Explanation of Solution
Based on the given the dot plot, it is clearly visible that the data is skewed towards the left side or negatively skewed. When the data negatively skewed the value of mean is always less than the median. Therefore, Mean < Median.
