find the mean of the data set shown in the table below. data set b 1.34 0.18 0.77 0.92 0.29

Explanation:

Step1: Recall mean formula

The mean $\bar{x}$ of a data - set $x_1,x_2,\cdots,x_n$ is $\bar{x}=\frac{\sum_{i = 1}^{n}x_i}{n}$, where $n$ is the number of data points and $\sum_{i=1}^{n}x_i$ is the sum of the data points. Here $n = 5$, $x_1=1.34$, $x_2 = 0.18$, $x_3=0.77$, $x_4=0.92$, $x_5=0.29$.

Step2: Calculate the sum of data points

$\sum_{i = 1}^{5}x_i=1.34 + 0.18+0.77+0.92+0.29=3.5$

Step3: Calculate the mean

$\bar{x}=\frac{3.5}{5}=0.7$

Answer:

$0.7$
