1. In a normal distribution, what proportion of cases fall (report to four decimal places):
(a) above z = +1.00?
(b) below z =-2.00?
(c) above z = 3.00?
(d) below z = 0?
(e) above z = -1.28?
(f) below z = -1.62?

(a) z = -1.00 and z = 1.00?
(b) z = -1.50 and z = 1.50?
(c) z = -2.28 and z = 0?
(d) z = 0 and z = 50?
(e) z = +.75 and z = 1.25?
(f) z = - 80 and z = -1.60?
