Question

Find the area under the standard normal curve between z=-1.57 and z=0.77. Round to four decimal places

Answer 1

Let Z be a standard normal random number.

The area under the standard normal curve between z=-1.57 and z=0.77 is same as the probability that Z is between -1.57 and 0.77

ans: the area under the standard normal curve between z=-1.57 and z=0.77 is 0.7212
