Explanation of Solution
Given:
For X:
Population mean
Population standard deviation
For Y:
Population mean
Population standard deviation
Calculation:
The mean value and standard deviation of the difference between Y and X can be computed as:
The average difference between the Y and X is expected to be 0.001.
