Question:
Use Table 3 on pages 334–335 to find the following:
(a) The probability that Z is greater than 0.7, P (Z > 0.7).
(b) The probability that Z is less than 0.7, P (Z < 0.7).
(c) The probability that Z is greater than 2.27, P (Z > 2.27).
(d) The probability that Z is greater than –1.35, P (Z > –1.35).
(e) The probability that Z is less than –1.35, P (Z < –1.35).
(f) The probability that Z is greater than 0.41 and less than 2.74, P (0.41 < Z < 2.74).
(g) The probability that Z is less than –0.82 and more than –1.98, P (–1.98 < Z < –0.82).
(h) The probability that Z is less than 1.53 and more than –0.69, P (–0.69 < Z < 1.53).
Until you are used to dealing with the Standard Normal Distribution you may find it helpful to make a small sketch of the distribution and identify on the sketch the z value(s)
of interest and the area that represents the probability you want.
(a) The probability that Z is greater than 0.7, P (Z > 0.7).
