Question
Suppose that the random variable z has a standard normal distribution. Find each of the following z points, and use the normal table to find each z point. (Round z0.02 and –z0.02 to 3 decimal places and other answers to 2 decimal places; Use the closest value of Z when there is not an exact match; if the Zvalues are equidistant, then average the two Z values. Negative values should be indicated by a minus sign.

z0.3 z0.44 z0.02 -z0.3 -z0.44 -z0.02Explanation / Answer
Z0.3 = -0.52
Z0.44 = -0.15
Z0.02 = -2.055
-Z0.3 = 0.52
-Z0.44 = 0.15
-Z0.02 = 2.055
