Question: To find a value of the standard normal random variable? z, called z 0 0?, such that ?P( z greater than z 0 z > z0?)=.1922, which of the following is? correct:

A. Tofind the correct z on the table two things must be? considered: 1) the area we are looking for is in the? "greater than" direction AND? 2) the area is only .1922? (less than half the? graph), so z 0 z0 must be on the right hand size of the graph. If z 0 z0 were located on the left size of the? graph, and we calculated the probability for the area? "greater than" z 0 z0?, the result would be larger than .5000.

B. Since this probability is looking only in the greater than? direction, the z must be on the right hand side of the graph.

C. To find the correct z on the? table, divide .1922 in? half, then find the appropriate z on the table.

D. Since the probabilty is smaller than? .5000, z 0 z0 must be located on the left hand side of the graph.
