Hi, i'm david and i'm here here is in the question.
00:03
Now let me bring up your question here.
00:06
In the question here we are going to discuss about the pami's testing.
00:11
Here, one tree that our finding is truly lower than the proportion, which is the 50%.
00:23
So therefore, we will see the known, the automated hypothesis, the h1.
00:30
The proportion, because when you test the number, the smaller than the 3 -1 will be the 80%, which is 0, and the answer must be the option d here.
00:44
On the number 7, i want to find the critical value because it will be the next new test, so that i found the critical value equal to the z minus z of the alpha, and we see that the alpha equal to the z -1 -0 fund.
01:01
And we look at the z table this one the equal to the minus 1 .6 .45.
01:08
So that's the answer for this question.
01:10
It will be equal to here, it will equal.
01:21
So we have the check in six people.
01:24
We don't have the one here but i believe the question using the d distribution.
01:31
So here i use the d.
01:35
Put that in minus 1 we preview and 4.
01:39
And then we will have it will be minus t and receive equal to the 206, minus 1 will be the 25 and 5 equal to the 0 1 .5...
