Expert Answer

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”

 Output:

fullscreen
Step 2

Question 5B: Obtain the variance for highway fuel efficiency.

Excel procedure to find the variance for highway fuel efficiency:

 Step 1: Enter the highway fuel efficiency values from B2:B71

Step2: In cell B72, enter the formula “=VARA(B2:B71)”

 Output:

fullscreen
Step 3

Question 5C: Obtain the IQR for engine size.

 Excel procedure to find the IQR for engine size:
