Answer:
The mean of this data set is [tex]\mu = 18.8[/tex]
Step-by-step explanation:
By definition, the mean of a data set [tex]x_1, x_2, x_3, ..., x_n[/tex] is
[tex]\mu = \frac{\sum^n_i x_i}{n}[/tex]
Where n is the total number of data.
In this case we have 10 data
14, 12, 21, 26, 19, 15, 22, 17, 24, 18
So the mean is:
[tex]\mu = \frac{14 +12 +21 +26 +19 +15 +22+ 17 +24 +18}{10}[/tex]
[tex]\mu = 18.8[/tex]
