Question

The ages of the patients in a doctor's surgery are: 27, 13, 16, 20, 41 and 9. Find the mean of this set of data. Another patient has just walked in and their age is 84. What is the mean of the patients now? How many patients are now over this mean age?

Answer 1

The mean is 30 and there are 2 patients over this age.

Explanation:

Add up 27+13+16+20+41+9+84=210

Then divide by the amount of numbers "7" so

210/7 is 30.

There are 2 patients over the age of 30.

Make sure that you are correct and do the problem twice.
