Step 1

Question 5A: Obtain the range for engine size.

 Excel procedure to find the range for engine size:

 Step 1: Enter the engine size values from A2:A71

Step2: In cell A72, enter the formula “=MAX(A2:A71)”

Step3: In cell A73, enter the formula “=MIN(A2:A71)”

Step4: In cell A74, enter the formula “=A72-A73”
