Given:
1.
Consider San Diego's plot.
Median = 70.
The minimum value =65 and maximum =77.5
The range = max-min
The range = 77.5-65=12.5
Interquartile range = 75-66=9
2.
Consider Boston's plot.
Median =59.
minimum =36 and maximum =82.
The range =Max-min
Range = 82-34= 48
Interquartile range = 74-43=31.
3.
Consider the Interquartile range of San Diego's set and Boston's set.
The interquartile range of San Diego's set = 9
The interquartile range of Boston's set = 31
Hence the Interquartile range of San Diego's set is less than the Interquartile range of Boston's set.
Consider the median of San Diego's set and Boston's set.
Median of San Diego's set = 70
Median of Boston's set = 59.
The median of San Diego's set is greater than the median of Boston's set.
