. Standard Normal Table. Answer the following questions relating to standard normal probabilities by using the table. Sketch the bell-curve showing appropriate Z-scores, and shaded areas. Show any operations taken such as subtractions, when answer does not come directly from table.

(a) P(Z > −1.65)

(b) P(Z < 1.28)

(c) P(1.28 < Z < 2.05)

(d) Z-score, a, such that P(Z < a) = .0060

(e) Z-score, b, such that P(−b < Z < b) = .7500
