Sagot :

Answer:

a. z = 1.0364

b. z = -0.2533

c. z = -0.6745

d. z = 0.2533

Explanation:

We can represent each option with the following diagrams

So, for each option, we need to find a z that satisfies the following

a. P(Z > z) = 0.15

b. P(Z < z) = 0.40

c. P(Z > z) = 0.75

d. P(Z > z) = 0.60

Then, using a normal table distribution, we get that each value of z is

a. z = 1.0364

b. z = -0.2533

c. z = -0.6745

d. z = 0.2533
