Step-by-step explanation:
Given : The set of data
18, 15, 22, 18, 25, 19, 23
To find: The mean of the data?
Solution :
Mean is defined as the sum of the number of observation by total number of observation.
[tex]M=\frac{\sum x_n}{n}[/tex]
[tex]M=\frac{18+15+22+18+25+19+23}{7}[/tex]
[tex]M=\frac{140}{7}[/tex]
[tex]M=20[/tex]
Therefore, The mean of the data is 20.
So, Option c is correct.
