Question

anduin casts a variety of healing spells. the number of health points that each of his healing spells restores is listed below. 43, 57, 30, 18, 26, 12 find the mean number of health points. health points show calculator

Explanation:

Step1: Sum the health points

To find the mean, first we sum all the values. The values are 43, 57, 30, 18, 26, 12. So we calculate \(43 + 57 + 30 + 18 + 26 + 12\).
\(43+57 = 100\), \(100+30 = 130\), \(130+18 = 148\), \(148+26 = 174\), \(174+12 = 186\).

Step2: Divide by the number of values

There are 6 values (since there are 6 healing spells). The formula for the mean \(\bar{x}=\frac{\sum_{i = 1}^{n}x_{i}}{n}\), where \(n = 6\) and \(\sum_{i=1}^{n}x_{i}=186\). So we calculate \(\frac{186}{6}\).
\(\frac{186}{6}=31\).
