# The Purposes of a Hypothesis Test

Not what you're looking for?

What is the purpose of a hypothesis test? What goes in the null hypothesis and what goes in the alternate hypothesis? Why is it inappropriate to put a sample statistic in the hypothesis?

If you are testing the hypothesis

H0: population proportion is .5
H1: population proportion is not .5,

and you get .52 for the sample proportion, can you reject the null hypothesis? Why or why not? If you are also told that the sample size is 50, can you now do a hypothesis test? If you can, check that the assumptions necessary to do a hypothesis test are satisfied, do the test, and state your conclusion.

##### Solution Summary
