Transcript
In this problem, we are given that there is a standard normal curve. So let's first draw a standard normal curve, and we are required to determine the area between the two values of Z, which are 0 .28 and 0 .77. So we see that for a standard normal distribution curve, this is symmetric about the Z value equal to 0. And the two points here, 0 .28, that would lie to the right of Z value equal to 0. And 0 .77, this would lie even to the right. And the area would be represented by this shaded portion here. And we see here that the area represented by A would be the probability that the Z value is greater than 0…
