five - number summary
min q1 median q3 max
1 275 533 933 2596
according to the 1.5 - iqr rule for outliers, how many low outliers are there in the data set?
choose 1 answer:

Explanation:

Step1: Calculate the IQR

The inter - quartile range (IQR) is $Q_3 - Q_1$. Given $Q_1 = 553$ and $Q_3=933$, so $IQR=933 - 553=380$.

Step2: Calculate the lower fence

The lower fence for outliers is $Q_1-1.5\times IQR$. Substitute the values: $553-1.5\times380=553 - 570=-17$.

Step3: Check for low outliers

The minimum value in the data set is 1. Since the minimum value 1 is greater than the lower fence of - 17, there are no low outliers.
