Problem 44B

Finding Critical Values. In Exercise, find the indicated critical value.

z0.03

Answer :

Step 1 :

Given , .

We have to find the critical value of Z = ?

Consider,

1 - = 1 - 0.03 0.97.

Then, we have to check the for the value 0.97 in standard normal table,

Which falls in 1.8th row and 8th column.

Therefore,the critical value of Z is given by z = 1.88
