z0.025

Problem 41BSC

Answer:

Step1 of 1:

We have .

We need to find the critical value of Z = ?

Consider,

1 - = 1 - 0.025 0.975.

Now,

we have to see in standard normal table where 0.975 falls,it falls row 1.9 under the column 6

Therefore,the critical value of Z is given by z = 1.96.

A graph of area under normal curve is given by
