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
The area under the standard normal curve to the right of z = 1.72 is 0.0427.
The standard normal curve is an asymmetric, bell-shaped curve where half of the data lies in the left of the center i.e. z=0, and half of the data lie in the right of the center.
As z= -1.72 is on the left side of the curve, the same way z = -1.72 will lie on the right side and at the same distance from the center i.e. z=0.
Because of symmetricity area which will fall to the right of z= 1.72 will be the same as the area to the left of z =-1.72
Therefore, the area under the standard normal curve to the right of
z = 1.72 is 0.0427.
