The first quartile of a data set is 72, and the third quartile is 92. Which of these values in the data set is an outlier? A.61

marishachu [46]

IQR = Q3 - Q1 = 92 - 72 = 20
20 * 1.5 = 30

72 - 30 = 42....outlier is anything below 42
92 + 30 = 122...outlier is anything above 122

so the outlier is 41
