Find the z score for which the area to the right is 0.27.

Using the normal distribution, it is found that the z-score is of z = 0.613.

In a normal distribution with mean and standard deviation , the z-score of a measure X is given by:

In this problem, the area to the right is of 0.27, which means that z has a p-value of 1 - 0.27 = 0.73, thus z = 0.613.

To find the Z score for a number to the right,

subtract the value from 1:

1-0.27 = 0.73

Now use a z-score table and look up 0.73.

0.73 is located at Z = 0.615
