Quizplus · Accepted Answer

The total area under the standard normal distribution curve is equal to 1. The shaded region represents the area to the right of z=0. Therefore, we need to find the probability that a standard normal random variable is greater than 0. This probability can be found using a standard normal table or calculator to be 0.5 + 0.2580 = 0.7580. Thus, the area of the shaded region is 0.7580.
