Answer:

The correct answer is:

(a) 0.0884

(b) 0.0190

(c) 0.9596

(d) 0.2921

Step-by-step explanation:

(a)

= P(1.26

= P(Z

= 0.9846-0.8962

= 0.0884

(b)

= P(2.05

= P(Z

= 0.9989-0.9798

= 0.0190

(c)

= P(-2.05

= P(Z

= 0.9798-0.0202

= 0.9596

(d)

= P(Z>0.55)

= 1-P(Z

= 1-0.7088

= 0.2912
