Answer to Problem 10WE
The total area under the curve is 1 and standard normal curve is symmetric about y -axis.
Explanation of Solution
Given information:
The fraction of data greater than a constant k is equal to 1 minus the fraction of data less than k .
Consider the provided information thatfraction of data greater than a constant k is equal to 1 minus the fraction of data less than k .
The total area under the curve and above x -axis is 1 and standard normal curve is symmetric about y -axis.
Therefore, for fraction of data greater than
