Answer:

28

Step-by-step explanation:

in order to find first quartile find median:

median =32

since there are 6 data points lets split the data set into 2 groups of 3 data points each

the median of the first group is the first quartile and the median of the second group is the third quartile

group 1: 16 28 28

median=28

1st quartile=28
