Question

You have found the following ages (in years) of all 5 gorillas at your local zoo:

8, 4, 14, 16, 8
What is the average age of the gorillas at your zoo? What is the standard deviation?

Answer 1

The average age of the gorillas at the zoo is 10 years. The standard deviation is about 4.83 years.

Step-by-step explanation:

To find the average age of the gorillas at the zoo, you add up all the ages and then divide by the total number of gorillas.

In this case, the sum of the ages is 8 + 4 + 14 + 16 + 8 = 50. There are 5 gorillas, so the average age is 50 ÷ 5 = 10 years.

To find the standard deviation, you can use a formula. However, it's easier to use a calculator or spreadsheet program.

In this case, the standard deviation is about 4.83 years.
