**Quote:**

The range for a list of measurements equals the greatest measurement minus the least measurement. The two lists of measurements, X and Y, combined consist of 30 measurements with a range of 25. What is the range for the measurements in list X?

1) The range for the 12 measurements in list Y is 20.

2) List X consists of 18 measurements.

Here There are 30 measurements in x and y.

Range of 30 measurements is 25.

Range of x=?

First of all we need to know the elements that are present in x.

Statement 1:From 1 we got to know that y has 12 measurements and x has 18.

Now Y has range 20:

we don't know what are the elements that make the range 25 overall and we don't even know the elements in x to find the range of x.

Statement 2:Same problem as A in statement 2.we don't know the elements.

From 1+2.

we don't know any extra information.

So, the Answer is

E
