Answer
Given that the correlation between the Calories and Protein and Calories and Carbohydrates are greater than 0.7, there is a reason to be concerned about multicollinearity.
Work Step by Step
In MINITAB, enter the calories values in C1, the protein values in C2, the fat values in C3 and the carbohydrates values in C4.
Select Stat -> Basic Statistics -> Correlation
In variables enter C1 C2 C3 C4. You may deselect "Display p-values"
Click OK.
Since more than one correlation between the explanatory variables is greater than 0.7, there is evidence that multicollinearity exists.
