Answer 4

Do you normally find the critical z-value by looking it up in a table?

Answer 5

Critical z values can be obtained by looking at an inverse normal probability table or by using technology. Which method are you expected to use?

Answer 6

We would also need to know if it is a right-tailed test, left-tailed test, or two-tailed test.

Answer 7

using technology

Answer 9

There is an inverse normal probability calculator here:

Just enter the value of alpha in the top box and leave the default values for the mean (0) and standard deviation (1) as they are.
