Answer 2

Hey Mate!

First, to find the mean, we have to add all the values and then divide the sum by the number of values given.

Here the number of values is 4, so we will divide by 4.

Now the sum of the values = 6.4 + 3.26 + 1.4 + 15

= 26.06

Now let's divide this by 4.

= 26.06/4 = 6.515.

Hope it helps :-)
