Question

Here is a set of data

2.4, 1.6, 3.2, 0.3, 1.5

Each piece of data is now doubled
Work out the new mean

Answer 1

The new mean is 3.6

Explanation:

Since each piece of data is now doubled that means the data is now

4.8, 3.2, 6.4, 0.6, 3

Add up all of the data which comes out to 18

Divide 18 by the number of numbers there are which is 5

This will get you 3.6 which is the new mean of the data
