Find the probabilities for the following PZ 156 P15 Solution

Find the probabilities for the following P(Z 1.56) P(-1.5

Solution

using talbes of Z distribution we will find those values of probability

a)

P( z <-2.12) = 0.0170

b) P( z > 1.56) = 0.0594

c) P( -1.35 <z< 2.56) = 1 - P(z < -1.35) - P(z > 2.56) = 1 - 0.0885 - 0.00523 = 0.90627
