Answer:
Kindly check explanation
Step-by-step explanation:
Given that:
Equation of regression line : y^ = 60.7 + 0.139x
x = payroll (in millions of dollars) and y = number of wins for Major League Baseball teams in 2016.
From the general regression equation:
y = mx + c
Where m = slope of regression line.
The slope (m) of the equation given is 0.139
The slope could be interpreted as ; for every per unit change in y (every win a major league baseball team has in 2016), the payroll in million dollar increases by a product of 0.139
The slope of a regression line is the average rate of change of the line.
The interpretation of the slope is: the rate of wins per payroll is 13.9%
From the question, we have:
[tex]\mathbf{\bar y= 60.7 + 0.139x}[/tex]
The equation of a linear regression is:
[tex]\mathbf{\bar y= c + mx}[/tex]
Where m represents the slope
So, by comparison:
[tex]\mathbf{m = 0.139}[/tex]
[tex]\mathbf{m = 13.9\%}[/tex]
This means that, the rate of wins per payroll is 13.9%
