Refer to the Baseball 2021 data that report information on the 30 Major League Baseball teams for the 2021 season.
a. In the data set, the year opened is the first year of operation for that stadium.

Develop a box plot with the new variable, stadium age. Are there any outliers? If so, which of the stadiums are outliers?
b. Using the variable salary create a box plot. Are there any outliers? Compute the quartiles using formula (4-1). Write a brief summary of your analysis.
c. Draw a scatter diagram with the variable wins on the vertical axis and salary on the horizontal axis. Compute the correlation coefficient between wins and salary. What are your conclusions?
d. Using the variable wins draw a dot plot. What can you conclude from this plot?
