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. Which statements are true? Select each correct answer. Dr. Cantwell’s patients’ ages and Dr. Singh’s patients’ ages vary about the same amount. Dr. Singh’s patients’ ages and Dr. Appiah’s patients’ ages vary about the same amount. Dr. Appiah’s patients’ ages vary less than do Dr. Singh’s patients’ ages. Dr. Appiah’s patients’ ages vary more than do Dr. Cantwell’s patients’ ages. Dentist Mean patient age MAD Appiah 43 9.7 Cantwell 29 13.9 Singh 41 14.1

Respuesta :

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


GARBAGE DAY!

The statement that asserts a true claim would be:

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

C). Dr. Cantwell’s patients’ ages and Dr. Singh’s patients’ ages vary about the same amount.

Mean

Given that,

Dentist        Mean age               Mean absolute deviation

Appiah           43                                    9.7

Cantwell        29                                   13.9

Singh                41                                    14.1

As per this,

We can deduce that,

The age of the patients of Dr. Appiah is distinctively different from the patients of Dr. Singh due to the higher deviation.

Also,

The variation in the age of Cantwell and Dr. Singh is almost similar as their deviation ranges very near to one another.

Thus, options A and C are the correct answers.
