Answer
$β_0=0.120$
$β_1=1.0997$
Work Step by Step
In MINITAB, enter the Rate of Return of S&P 500 values in C1 and in C2 enter the Rate of Return in United Technologies values.
Select Stats -> Regression -> Regression -> Fit Regression Model
Enter C2 in "Responses" and C1 in "Continuous Predictors"
The least-squares regression line ($ŷ =b_1x+b_0$) will be shown in "Regression Equation", where C2 is ŷ (Rate of Return in United Technologies values) and C1 is x (Rate of Return of S&P 500)
$ŷ =1.0997x+0.120$
That is:
$b_0=0.120$ and $b_1=1.0997$
$b_0$ is the estimate for $β_0$ and $b_1$ is the estimate for $β_1$.
