The economic structure of Major League Baseball allows some
teams to make substantially more money than others, which in turn
allows some teams to spend much more on player salaries. These
teams might therefore be expected to have better players and win
more games on the field as a result. Suppose that after collecting
data on team payroll (in millions of dollars) and season win total
for 2019, we find a regression equation:
Wins = 81.77 + 0.134Payroll - 0.047League
Where League is an indicator variable that equals 0 if the team
plays in the National League or 1 if the team plays in the American
League.
a) Calculate the predicted number of wins for a National League
team with a payroll of $103 million
b) Calculate the predicted number of wins for an American League
team with a payroll of $97 million
c) Suppose we plotted the data and drew the regression lines for
National League and American League teams. What would be the slope
of the line for American League teams?
d) What would be the intercept of the line for the National League
teams?

Think about Major League Baseball! The
owners of the major league teams are arguing that they may have to
shut the season down unless the players agree to a significant
salary cut. If the players agree, the owners will be able to play
games this season.
Explain loss-minimization and shut
down cases for perfectly competitive firms. Explain why baseball
owners may have to resort to a shut-down case and why they may be
able to use a loss-minimization case.

Major League Baseball (MLB) consists of teams that play in the
American League and the National League. MLB collects a wide
variety of team and player statistics. Some of the statistics often
used to evaluate pitching performance are as follows:
ERA: The average number of earned runs given up by the pitcher
per nine innings. An earned run is any run that the opponent scores
off a particular pitcher except for runs scored as a result of
errors.

In Major League Baseball, the American League (AL)
allows a designated hitter (DH) to bat in place of the pitcher, but
in the National League (NL), the pitcher has to bat. However, when
an AL team is the visiting team for a game against an NL team, the
AL team must abide by the home team’s rules, and thus, the pitcher
must bat. A researcher is curious if an AL team would score more
runs for games in which the...

Refer to the Baseball 2016 data, which report information on the
30 Major League Baseball teams for the 2016 season. Refer to the
variable team salary. Prepare a report on the team salaries. Be
sure to answer the following questions in your report. Around what
values do the data tend to cluster? Specifically what is the mean
team salary? What is the median team salary? Is one measure more
representative of the typical team salary than the others? What is...
