Answer
$Q_{1} = 36\\
Q_{2} = 40.5\\
Q_{3} = 46.5$
IQR = 10.5
Outliers = 19
Work Step by Step
Sort the data in ascending order
Middle value is Median and Q2 or 50% of the data
Middle value of the values below Q2 will be Q1 or 25% of the data
Middle value of the values above Q2 will be Q3 or 75% of the data
Values above 1.5 IQR + Q3 will be outliers
