Calculations for a hypothesis test depend on what kind of test you are doing. There are many different kinds of tests. The significance level is used to reject or fail to reject the null hypothesis in a hypothesis test. If you use a z-table for a one-tailed z-test at 0.05 level of significance (for example), then you will have a value of z = -1.645 or it could be z = 1.645, depending on the direction of the tail. This will determine where you "draw the line" to reject the null hypothesis.
I hope this will help and is what you were asking.
Explain the calculations for a hypothesis test and discuss how you would test for signifiance at the 0.05 level
