Answer
Answer = 0.7157
Work Step by Step
We want to find the area to the RIGHT of z = -0.57 i.e. we want to find P(z > -0.57)
First we use the standard normal distribution table to find the area to the LEFT of z = -0.57. This is 0.2843
Secondly, we must remember that the area under the standard normal curve is 1. So we calculate 1 - 0.2843, which gives us 0.7157.
