Question

find the mean for the following group of data items. 135, 75, 105, 75, 95 the mean is (type an integer or a decimal.)

Explanation:

Step1: Calculate the sum of data items

$$135 + 75+105 + 75+95=485$$

Step2: Count the number of data items

There are \(n = 5\) data items.

Step3: Calculate the mean

The formula for the mean \(\bar{x}=\frac{\sum_{i = 1}^{n}x_{i}}{n}\), so \(\bar{x}=\frac{485}{5}=97\)

Answer:

\(97\)
