Question

Use the following data set to answer the question below.50 60 8090 50 7040 50 80What is the mean for the data set? (Round your answer to the nearest tenth, ifnecessary.)

Answer 1

Given The following data set:

50 60 80

90 50 70

40 50 80

We will find the mean of the data as follows:

`mean=\frac{sum\text{ }of\text{ }the\text{ }data}{number\text{ }of\text{ }the\text{ }data}`

We will find the sum of the data as follows:

`sum=50+60+80+90+50+70+40+50+80=570`

The number of the data = 9

So, the mean will be as follows:

`mean=(570)/(9)=63.333`

Rounding to the nearest tenth

So, the answer will be The mean = 63.3
