Refer to the Baseball 2009 data, which reports information on the 30 Major League Base- ball teams for the 2009 season. Set up three variables:

• Divide the teams into two groups, those that had a winning season and those that did not. That is, create a variable to count the teams that won 81 games or more, and those that won 80 or less.

• Create a new variable for attendance, using three categories: attendance less than 2.0 million, attendance of 2.0 million up to 3.0 million, and attendance of 3.0 million or more.

• Create a variable that shows the teams that play in a stadium less than 15 years old versus one that is 15 years old or more.

A Survey of Probability Concepts

Answer the following questions.

A. Create a table that shows the number of teams with a winning season versus those with a losing season by the three categories of attendance. If a team is selected at random, compute the following probabilities:

1. The team had a winning season.

2. The team had a winning season or attendance of more than 3.0 million.

3. The team had a winning season given attendance was more than 3.0 million.

4. The team has a winning season and attracted fewer than 2.0 million fans.

B. Create a table that shows the number of teams with a winning season versus those that play in new or old stadiums. If a team is selected at random, compute the following probabilities:

1. Selecting a team with a winning season.

2. The likelihood of selecting a team with a winning record and playing in a new stadium.

3. The team had a winning record or played in a new stadium.
