Testing hypotheses about proportions - The reasoning of hypothesis testing

4 important questions on Testing hypotheses about proportions - The reasoning of hypothesis testing

What is meant with the alternative hypothesis?

It contains the values of the parameter we consider plausible when we reject the null.

What is a two-sided alternative?

We are equally interested in deviations on either side of the null hypothesis value. 

Which steps should you take to test a hypothesis?

-State the null hypothesis
-Specify the model you will use to test the null hypothesis and the parameter of interest.
-Place the actual calculation of the test statistic from the data.
-Draw a conclusion.
-Find alternative alternatives.
