2. CHAPTER 12 Inference for Proportions

4. Steps are the same as other hypothesis tests.
State null and alternative hypotheses
Ho: p=p0 Ha: p>p0, or p<p0 or p≠p0
where p0= accepted value
Calculate your z test statistic
Find your P-value on table A, it is interpreted the same way.
State whether you reject or fail to reject H0.
Relate it back to your problem
State probability of getting a as extreme as you did if Ho is true.

6. Confidence Level is interpreted - If we take multiple samples of the same size from the same population 95% of the intervals will contain the true population proportion.
Confidence Intervals are interpreted - We are 95% confident that the interval will capture the true population proportion or
