Question

mean, median, mode, & range
what is the mean of the data?
4.8, 2.3, 3.1, 5.6, 2.3
round to the nearest hundredth if necessary. enter the word none if there isnt one

Explanation:

Step1: Recall mean formula

The mean $\bar{x}=\frac{\sum_{i = 1}^{n}x_{i}}{n}$, where $x_{i}$ are data - points and $n$ is the number of data - points.

Step2: Calculate the sum of data

$\sum_{i=1}^{5}x_{i}=4.8 + 2.3+3.1 + 5.6+2.3=18.1$

Step3: Determine the number of data

$n = 5$

Step4: Calculate the mean

$\bar{x}=\frac{18.1}{5}=3.62$

Answer:

$3.62$
