Question

2 find the mean of the following set of numbers. 8,5,9,5,5,7,3 mean =

Explanation:

Step1: Calculate the sum of the numbers

$$8 + 5+9 + 5+5 + 7+3=42$$

Step2: Count the number of elements

There are \(7\) 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 and \(n\) is the number of elements. So \(\bar{x}=\frac{42}{7}\)

Answer:

\(6\)
