(a) Find the area under the standard normal curve that lies between z= −2.39 and z= −1.27.

(b) Find the area under the standard normal curve that lies outside the interval between z= −1.36 and z= 1.68.

(c) Find the area under the standard normal curve to the left of z= 0.74.

(d) Find the area under the standard normal curve to the right of z= 1.17.
