So in this question here, we need to first determine what kind of test we are going to use.
00:05
So because we are working with proportion, we are going to say that we are going to use a proportion test here.
00:12
The parameter that we have here is the proportion that we have, but in the population, so the proportion of adults here in a certain region.
00:26
Basically, i'm putting the information that the question gave us.
00:29
So i want to know about the drinking habits of this certain region of a country, and we are interested in the proportion of those that drink in this specific location.
00:44
So we should say that we want the proportion for all those that live in this area.
00:49
Then in the other part, we should say what kind of test we want to test.
00:54
So because they want to check if it is equal or not to what they say that is 0 .26, we are just doing a two -tail test, because we are not saying if it is greater or smaller than that value...
