Question

find the mean for the scores: 3,860, 5,500, 8,560, 4,200, 5,340. the mean for the scores is □.

Explanation:

Step1: Recall mean formula

The mean $\bar{x}=\frac{\sum_{i = 1}^{n}x_{i}}{n}$, where $x_{i}$ are the data - points and $n$ is the number of data - points. Here, $n = 5$, and $x_1=3860$, $x_2 = 5500$, $x_3=8560$, $x_4 = 4200$, $x_5=5340$.

Step2: Calculate the sum of data - points

$\sum_{i = 1}^{5}x_{i}=3860 + 5500+8560+4200+5340=27460$.

Step3: Calculate the mean

$\bar{x}=\frac{27460}{5}=5492$.

Answer:

$5492$
