Find the value of z_0 for the standard normal variable Z that satisfies each of the following statement. (If you use Table A, report the value of z_0 that comes closest to satisfying the condition). In each case, sketch a standard normal curve with your value of z_0 marked on the axis and shade the relevant area under the curve.
a. 32% of the observations fall below z_0
b. 42% of the observations fall above z_0
c. 95% of the observations fall between -z_0 and z_0
d. 98% of the observations fall between -z_0 and z_0
