The area under the standard normal curve that lies to the le

The area under the standard normal curve that lies to the left of -1.96 is 0.0250. Without consulting a the table giving areas under the standard normal curve, determine the area under the standard normal curve that lies to the right of 1.96.

Solution

Since normal curve is symmetric about its mean (which is zero in this case), area on left of -1.96 is same as that on right of 1.96, i.e, 0.0250
