So the first thing that we're going to do is complete the sentence so we can actually check that we can perform the hypothesis testing.
00:10
So the first thing that we're going to do is compute what is the sample size times the value that we are assuming has to be the population value as the proportion.
00:20
So if you compute this using the data, we have that the sample size is 840, the value in the population is 0 .023, and we do 1 minus this value to get that this result is 18 .86.
00:37
So that's what we need to put as the equal, which indeed, this is greater than 10, right? and then we completed that we can actually assume, usually we can because the sample size is not that high.
00:50
So we can indeed assume that we have less than 5 % of the population size.
00:56
And because we are considering like a clinical trial, usually what they use is a random sample.
01:03
So we can indeed say that we can reasonably assume here that our sample is indeed random.
01:14
Okay.
01:15
And by doing, by assuming or checking all these facts, we can see that the requirements that we need to perform this hypothesis testing, they are satisfied.
01:27
Then in terms of like hypothesis, indeed, we are comparing if the proportion is equal to what they are saying, or if it is greater than this value.
01:39
Usually it's like implicit here that we have also the less sign here...
