Hi, i'm david and i'm here to help you answer your question.
00:03
Now let me bring up your question here.
00:06
In the question here we are going to discuss about the hybrid testing.
00:10
Here i want to test the claim that among the smokers who try to quit with the nicotine path therapy, the majority are smoking one year after the treatment.
00:25
So, they will define the proportion of the people who smoking one year after the treatment.
00:31
After the treatment will be the p.
00:33
Then the known hypothesis for this case will be the p equal to the 0 .15 versus the alternative hypothesis p will be greater than the 0 .15.
00:43
In this question here, we have the 36 was smoking one year after treatment and 33 was not smoking over one year of the treatment.
00:52
The value of 36 will be our interest and we define as an x.
00:57
So therefore, we have the end in this case.
00:59
It will be the 36 plus the 33 and equal to the 69, the x equal to the 36.
01:08
From this one we can find the phex equal to x over n equal to the 36 over 69.
01:15
And then we get equal to the 0 .5 to 2.
01:23
And then the next step, we will need to be able to find the test statistics.
01:27
And the test statistics equal to the p heart minus the p.
01:31
B divided by square root of the p times 1 minus p over the n.
01:37
We have b hot equal to 0 .5 2 2p.
01:41
B equal to the 0 .5, divided by square root the 0 .5 times 1 minus 0 .5.
01:47
Over the n will be the 69...
