The table below shows the number of hours some business people in two states spend in meetings each week:
state a
21 23 24 22 24 25 23 23 22
state b
24 22 20 23 23 50 20 46 21

part a: create a five-number summary and calculate the interquartile range for the two sets of data.

part b: are the box plots symmetric? justify your answer.

Arrange data set in ascending order:
State A: 21, 22, 22, 23, 23, 23, 24, 24, 25
State B: 20, 20, 21, 22, 23, 23, 24, 46, 50

                               State A             State B
minimum                21                      20
1st Quartile            22                      20.5
median                   23                      23
3rd Quartile           24                      46
maximum               25                      50
IQR                          2                        25.5
