Refer to the Baseball 2016 data, which reports information on the 2016 Major

League Baseball season. Let attendance be the dependent variable and total team salary

be the independent variable. Determine the regression equation and answer the

following questions.

a. Draw a scatter diagram. From the diagram, does there seem to be a direct relationship

between the two variables?

b. What is the expected attendance for a team with a salary of $100.0 million?

c. If the owners pay an additional $30 million, how many more people could they expect

to attend?

d. At the .05 significance level, can we conclude that the slope of the regression line is

positive? Conduct the appropriate test of hypothesis.

e. What percentage of the variation in attendance is accounted for by salary?

f. Determine the correlation between attendance and team batting average and between

attendance and team ERA. Which is stronger? Conduct an appropriate test of

hypothesis for each set of variables.
