(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.
