Answer
Since the correlation between Height and Weight is greater than 0.7, there is reason to be concerned with multicollinearity.
Work Step by Step
In MINITAB, enter the Height values in C1, the Weight values in C2 and the Head Circumference values in C3.
Select Stat -> Basic Statistics -> Correlation
In variables enter C1 C2 C3. You may deselect "Display p-values"
Click OK.
Since the correlation between Height and Weight is greater than 0.7, there is evidence that multicollinearity exists.
