Question

If the area under the standard normal curve to the left of zequalsminus1.72 is​ 0.0427, then what is the area under the standard normal curve to the right of zequals​1.72?

Answer 1

Answer: 0.0427

Step-by-step explanation:

Given : The area under the standard normal curve to the left of z = -1.72 is​ 0.0427

We know that the normal curve is a bell shaped curve that is symmetric such that half of the data falls to the left of the mean (Mean lies at the middle of the curve) and half of data falls to the right.

Now, z=-1.72 lies on the left side and z=1.72 lies right side.

Since, normal curve is symmetric and the magnitude of the values if same , then the area under the standard normal curve to the left of z = -1.72 is​  equals to the area to the right of z = 1.72 is 0.0427

Therefore, the area under the standard normal curve to the right of z = 1.72  is 0.0427
