Answer 1

Mean = 3.5

Explanation:

The given data is :

4.5,5, 3.5, 2, 2.5

We need to find the mean of the given data.

We know that,

Mean = sum of observations/total no. of observations

Here,

Total no. of observations = 5

Sum of observations = 4.5 + 5+ 3.5+ 2+ 2.5 = 17.5

Mean,

`m=(17.5)/(5)\\\\m=3.5`

Hence, the mean of the data set is equal to 3.5.
