Answer 1

15 can vary by 2%, this means that the range of values you can observe are 2% below 15 and 2% above 15.

First, you have to determine how much does the percentage represents with regards to the value of reference. To do so, you have to calculate the 2% of 15:

-Multiply 2 by 15 and divide the result by 100

`(2\cdot15)/(100)=(30)/(100)=3`

The 2% of 15 is 3, which means that the range of values you are looking for is 3 units below 15 and 3 units above.

The minimum value of the range: subtract 3 to 15

`15-3=12`

The maximum value of the range: add 3 to 15

`15+3=18`

The range of allowable values is [12;18]
