Question

Find the indicated critical value. z 0.07 Click to view page 1 of the table.  z 0.07 equals nothing ​(Round to two decimal places as​ needed.)

Answer 1

To of solving the problem of indicated critical value To solve for Zα where α is the area to the right of the Standard Normal curve at point Z ...

We know our table for Z scores gives us area to the left, so what we do is "convert" the question, to have is ask for the area to the left.

So, we know that the total area under the curve is equal to 1.

Now we solve for 1−α which will give us the area to the left of our curve. which then becomes more simple to solve for Z.

Thus for Z0.07 we have α=0.07, then we look for 1−α=1−0.07=0.93

So now we solve for Z where Φ(Z)=0.93

we take a look at our table, and get the answer that Φ(1.48)=0.93

Hence,

Z 0.07 = 1.48

Thank you.
