To write: a few sentences comparing the given two distributions.
Answer to Problem 60E
Shape: both distributions are right-skewed.
Center: Phillies is smaller than the Yankees.
Spread: Phillies is smaller than the Yankees.
Explanation of Solution
Given:
Calculation:
The graph below shows the 2008 salary distributions for the Yankees and the Phillies:
The histograms of salary distribution for the two teams during the 2008 season shows that both the distributions are skewed towards right but the distribution of Yankees has greater spread as compare to that of Phillies. The spread of Yankees varies from 0 to 32000000 and that of Phillies is from 0 to 16000000. Both Yankees and Phillies have peak between 0 to 4000000.
The graph shows that majority of the Phillies have salary less than 8000000 and very few have salary above 8000000 but in case of Yankees many have the salary between 12000000 to 16000000 and several have salary above 3200000.
Conclusion:
Therefore,
Shape: both distributions are right-skewed.
Center: Phillies is smaller than the Yankees.
Spread: Phillies is smaller than the Yankees.
