Question

For a standard normal distribution, find:P(-1.57 < z < 1.59)Express the probability as a decimal rounded to 4 decimal places.

Answer 1

Find out

P(-1.57 < z < 1.59)

we have

z1=-1.57

z2=1.59

using a z-score table value

we have that

P(-1.57 < z < 1.59)= 0.88588

rounded to 4 decimal places

The answer is 0.8859
