Answer to Question #295157 in Statistics and Probability for MayMay

Question

1.The curve between 0 and -2.0?

2.The curve to the right of 1.5

Answer 1

1. Using the normal tables we have

z(0) = 0.50000

z(-2.0) = 0.02275

This we have ( 0.50000 - 0.02275) = 0.47725 which is the required solution.

2. Using normal tables we have

z(1.5) = 0.93319

Thus the curve to the right is given as

( 1 - 0.93319) = 0.06681 which is the required solution.
