Answer:
21, 30 and 2.
Step-by-step explanation:
To find the mean you need to add up all the ages and divide them by however many there are.
In this case it's 27 + 13 + 16 +20 +41 + 9 = 126
126 divided by 6 = 21 so that's your answer.
Since another patient arrived we need to do 126 + 84 = 210. We need to remember that we have 7 patients now so we are going to do,
210 divided by 7 = 30.
Lastly, out of all the ages only 2 are over 30. The patient who is 41 and the new patient who is 84.
Hope that helps. x
