Step 1: Think of a problem that you may be interested in that deals with a comparison of two population proportions. Propose a hypothesis test question that compares these two proportions.
Step 2: Gather appropriate data including referenes and answer using statcrunch including hypothesis statement.
For example only, you may believe that the proportion of adults in California who are vegetarians is more than the proportion of adults in New Hampshire who are vegetarians. In two independent polls, you may find that 109 out of 380 California residents are vegetarians and 39 out of 205 New Hampshire residents are vegetarians.
