Use the appropriate table to answer the following questions: a.What value for z is such that the area under the standard normal curve to the left of that value is .9080? b.What value for z is such that the area under the standard normal curve to the right of that value is .1210?

Use the appropriate table to answer the following questions a What value for z is such that the area under the standard normal curve to the left of that value is .9080? b. What value for z is such that the area under the standard normal curve to the right of that value is .1210?

Explanation / Answer

We have given left sided area = 0.9080 and we have to find z value using z table.

Search 0.9080 or nearest value in the body of the table.

So we get z = 1.33

b) In table we have given left sided z value.

We have given right side area = 0.1210

So left sided area = 1 - 0.1210 = 0.879

Search 0.879 or nearest value in the body of the table.

We get z = 1.17
