find the critical value Z α/2 when the confidence level is 92%.

Expert Solution

Solution:

We have to find critical value when the confidence level is 92%.

c = confidence level = 0.92

then

thus

Look in z table for Area = 0.0400 or its closest area and find z value.

Area 0.0401 is closest to 0.0400 and it corresponds to -1.7 and 0.05

Thus z = -1.75

For confidence level ,we use absolute z value.

that is z = 1.75

Thus
