Answer 1

Answer:

The mean of the given data set is 5.5

Step-by-step 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,

$Mean =\displaystyle\frac{17.5}{5} = 3.5$

Thus, the mean of the given data set is 5.5
