Question

Find the area under the standard normal curve with respect to each of the following (using the z-table). Draw a drawing of each of them. (i) between z30 and 230.78​

Answer 1

Before you can solve for the area under a normal curve, you must be able to imagine what the area looks like. The best (albeit optional) way do this is to make a sketch. For example, let’s say you were give a z-score and were asked to find the area between that score and z=0 (the mean). Your sketch might look like this:

area under a normal curve

Find an area from z=0 to z=?
