Answer
$ŷ =-0.002889x+0.88607$
Work Step by Step
In MINITAB, enter the number of colas per week in C1 and in C2 enter the bone mineral density values.
Select Stats -> Regression -> Regression -> Fit Regression Model
Enter C2 in "Responses" and C1 in "Continuous Predictors"
The least-squares regression line ($ŷ =b_1x+b_0$) wil be shown in "Regression Equation", where C2 is $ŷ $ (bone mineral density) and C1 is $x$ (number of colas per week).
