Question

what is the mean of the set of numbers 17, 17, 11, 10, 1, 20, 17, 17

Explanation:

Step1: Find the sum of the numbers

$$17 + 17+11 + 10+1+20+17+17=100$$

Step2: Count the number of elements

There are \(8\) numbers in the set.

Step3: Calculate the mean

The formula for the mean \(\bar{x}=\frac{\sum_{i = 1}^{n}x_{i}}{n}\), where \(\sum_{i = 1}^{n}x_{i}\) is the sum of the data and \(n\) is the number of data points. So, \(\bar{x}=\frac{100}{8} = 12.5\)

Answer:

\(12.5\)
