To solve the shape of distribution decide.
Answer to Problem 15E
Histogram of Town A = Skewed Left
Histogram of Town B = Skewed Symmetric
Variation of Town B is greater than Town A.
Explanation of Solution
Given information: Shape of distribution
Calculation:
A distribution is called skewed left if, as in the histogram above, the left tail (smaller values) is much longer than the right tail (larger values).
If the data are symmetric, they have about the same shape on either side of the middle. In other words, if you fold the histogram in half, it looks about the same on both sides.
Histogram of Town A = Skewed Left
Histogram of Town B = Skewed Symmetric
Skewness is either positive or negative, depending on whether the more data on the right side of the mean value or the left, respectively. The bigger the value of the skewness score, the higher variation of the data in the positive (respectively. negative) direction.
Hence,
Variation of Town B is greater than Town A.
