Find a value with a graph, z0, such as:

a) P(z ≥ z0) = 0.06

b) P (z > z0) = 0.85

c) P (-z0 < z < z0) = 0.88

Solutions

Expert Solution

Solution:

Given that,

Using standard normal table,

a) P(z z0) = 0.06

P(z z0) = 1 - 0.06

P(z z0) = 0.94

z₀ = 1.55

b) P(z z0) = 0.85

P(z z0) = 1 - 0.85

P(z z0) = 0.15

z₀ = -1.04

c) P (-z0 < z < z0) = 0.88

P(Z < z0) - P(Z < z0) = 0.88

2P(Z < z0) - 1 =0.88

2P(Z < z0) = 1 + 0.88

2P(Z < z0) = 1.88

P(Z < z0) = 1.88 / 2 = 0.94

P(Z < z0) = 0.94

z0 = 1.55
