Final answer:
To find the mean payroll of the American League East division teams in 2018, sum the individual team payrolls and divide by the number of teams, resulting in a mean of $151.5 million.
Step-by-step explanation:
To calculate the mean payroll of the teams in the American League East baseball division for 2018, you would need to add the payrolls together and then divide by the number of teams.
- Boston Red Sox: $228 million
- New York Yankees: $177.5 million
- Toronto Blue Jays: $156.7 million
- Baltimore Orioles: $124 million
- Tampa Bay Rays: $71.3 million
Add these figures up:
$228 + $177.5 + $156.7 + $124 + $71.3 = $757.5 million
Then divide by the number of teams (5):
$757.5 million ÷ 5 = $151.5 million
So, the arithmetic average, or mean, of the 2018 payrolls for each team in the American League East baseball division is $151.5 million.
