Question
Shown to the right are the histogram and summary statistics for the number of camp sites at public parks in a particular state. Use this information to complete parts a through d below.
1.) How many parks would you classify as outliers? Explain.
A.There are three outliers because three data values are more than 3 standard deviations from the mean.
B.There are two outliers because two data values are either more than 1.5 IQRs below Q1 or more than 1.5 IQRs above Q3.
C. There are no parks that would be classified as outliers.
D. There are three outliers because three data values are either more than 1.5 IQRs below Q1 or more than 1.5 IQRs above Q3.
E. There are two outliers because two data values are more than 3 standard deviations from the mean.

IQR = Q3 - Q1 = 72 - 26 = 46
Hence,
Usual values range
= (26 - 1.5*46, 72 + 1.5*46)
= (-43, 141)
Hence,
There are three outliers.
Option D is correct.
