The correct option is B No, because the ratio of the difference in the medians to the IQR is less than 2.
Basketball Players:
Median distance =172m
Lower quartile =166m
Upper quartile =176m
IQR =176−166=10m
Swimmers:
Median distance =188m
Lower quartile =180m
Upper quartile =190m
IQR =190−180=10m
Since the IQR for both is the same, we can now compare the two data sets.
Difference in the medians =|188−172|=16
The ratio of the difference in the medians to the IQR =1610=1.6
Since the ratio of the difference in medians to the IQR is less than 2, we can say that swimmers are not significantly faster than basketball players.
Hence, the answer is option B.
