Answer:
1. z=0.44
Explanation:
Obviously a graph can only give us so much information. The above graph can tell us the area under the curve for one (z = -1 to 1), two (z = -2 to 2) and three (z = -3 to 3) standard deviations from the center. But what about if we want to know the area between z = -0.78 and z = 0.78? Or z = -1.2 and z=0.44? That’s where the z-table comes in. It tells us the area under the standard normal curve for any value between the mean (zero) and any z-score.
