Please answer both questions and I will rate if both answers are correct.
Answer - 1: From the z table output, the required areas will be:
A) Area = 0.4893
b) Area = 0.4789
c) Area = 0.8944
Answer - 2: A) P(X < 70000)
= P(z < (70000 - 76600)/3000)
= P(z < -2.2)
= 0.0139
B) P(X > 79600)
= P(z > (79600 - 76600)/3000)
= P(z > 1)
= 0.1587
