Question

1. find the mean (average) of 15, 16, 14, 13, and 12.

Explanation:

Step1: Calculate the sum of the numbers

$$15 + 16+14 + 13+12=70$$

Step2: Divide the sum by the number of values

There are \(n = 5\) values. The mean formula is \(\bar{x}=\frac{\sum_{i = 1}^{n}x_{i}}{n}\). So \(\bar{x}=\frac{70}{5}=14\)

Answer:

\(14\)
