Answer 1

The mean of the given data set is 5.5

Explanation:

We are given the following data in the question:

4.5,5,3.5,2,2.5

Formula:

`Mean = \displaystyle\frac{\text{Sum of all observations}}{\text{Total number of observation}}`

Putting values, we get,

`Mean =\displaystyle(17.5)/(5) = 3.5`

Thus, the mean of the given data set is 5.5
