The correct answer would be option D, 77 Years Old.
The administrator of a large assisted living facility wanted to know the average age of the residents living at the facility. He randomly selected 12 residents and determine their ages as given in the question. The average age of the sample of residents is 77.
Step-by-step explanation:
If we want to find out the average of anything, we simply add all the variables given, and then divide it with the quantity of the sample. In this question, the sample variable is the age of the residents living in the facility. So the sample is given below:
Sample ages: 80, 65, 75, 83, 68, 73, 88, 79, 94, 72, 79, 68
Quantity of sample: 12
Average age = Sum of sample / Quantity of Sample
(80 + 65 + 75 + 83 + 68 + 73 + 88 + 79 + 94 + 72 + 79 + 68) / 12
= 924/12
= 77
So average age of the residents living in the facility is 77.
