Question

Find the probability of the standard normal random variable Z.
P(Z < 1.49)

A) 0.9319

B) 0.0681

C) 0.6879

D) 0.3121

Answer 1

Answer #1

Using standard normal table,

P(Z < 1.49) = 0.9319

To see the z value 1.40 in the row and 0.09 in the column of the z table the cumulative

probability is 0.9319
