Answer:

Option B is right.

Step-by-step explanation:

Given that Three dentists wanted to compare the ages of their patients. They each calculated their patients’ mean age and the mean absolute deviation of their ages. They displayed the results in a table.  

Dentist      Mean      MAD

Appiah         43         9.7

Cantwell       29       13.9

Singh            41         14.1

Mean absolute deviaiton is a measure of deviations of all entries from the mean.

We find that maximum variation is that of Singh followed by Cantwell and Appaiah.

Option A is wrong as Dr. Appiah’s patients’ ages do not vary more than do Dr. Cantwell’s patients’ ages.  

B. is true.

Dr. Appiah’s patients’ ages vary less than do Dr. Singh’s patients’ ages.  

C is false  Dr. Cantwell’s patients’ ages and Dr. Singh’s patients’ ages vary about the same since tey are 13.9 and 14.1 hence different.

15) about 200 students loved music. You would round the 398 to 400 and the 52% to 50%, which is half.
16) They would cost the same because adding all of the discount together for the first computer would equal 30% which is the same amount as the second computer.

Hope this helped you!
