Question

find the mean, $overline{x}$, of the data. 251, 224, 237, 255, 268 $overline{x}=$

Explanation:

Step1: Sum the data

$$251 + 224+237 + 255+268$$
$$=(251+224)+237+(255 + 268)$$
$$=475+237+523$$
$$=475+(237 + 523)$$
$$=475 + 760$$
$$=1235$$

Step2: Divide by the number of data points

There are \(n = 5\) data points. The formula for the mean \(\bar{x}=\frac{\sum_{i = 1}^{n}x_{i}}{n}\). So \(\bar{x}=\frac{1235}{5}=247\)

Answer:

\(247\)
