Given The following data set:
50 60 80
90 50 70
40 50 80
We will find the mean of the data as follows:
[tex]mean=\frac{sum\text{ }of\text{ }the\text{ }data}{number\text{ }of\text{ }the\text{ }data}[/tex]We will find the sum of the data as follows:
[tex]sum=50+60+80+90+50+70+40+50+80=570[/tex]The number of the data = 9
So, the mean will be as follows:
[tex]mean=\frac{570}{9}=63.333[/tex]Rounding to the nearest tenth
So, the answer will be The mean = 63.3
