Question

use the data in the following table to answer the questions below. daily earnings $25 $26.50 $20 $23.50 $20 problem 1 2 3 4 find the mean. $20 $23 $23.50 $26.50

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. Here $n = 5$, and $x_1=25$, $x_2 = 26.50$, $x_3=20$, $x_4=23.50$, $x_5 = 20$.

Step2: Calculate the sum of data - points

$\sum_{i = 1}^{5}x_{i}=25 + 26.50+20+23.50+20=115$.

Step3: Calculate the mean

$\bar{x}=\frac{115}{5}=23$.

Answer:

$23$
