Answer:
mean = 16.7
median = 16
iqr = 15
Step-by-step explanation:
if you arrange values in numeric order you will see the middle value, median, is 16
the median of the lower half of data (first quartile) is 8
the median of the upper half of data (third quartile) is 23
interquartile range = 3rd quartile minus 1st quartile
