Hi, i'm david and i'm here to hold you into your question.
00:03
Now let me bring up your questions here.
00:06
In the question we are going to discuss about the re -based acting.
00:10
Here, when you test the claim that the probability that the home twin wings is greater than one half.
00:10
Here i want to test the claim that the probability that the home 3 wings is greater than 1 half.
00:18
So it means that we will have the known hypothesis.
00:21
When the proportion will be small equal to a half, and then we will have the alternative hypothesis.
00:31
The proportion will be greater than a half.
00:34
Now, in this question we are given the symbol n equals to the 54, and the x it will equal to the to the 28.
00:43
From here we can find the sum of a portion pinhart equal to x over n.
00:50
So equal to the 28 over 54.
00:53
Then we get equal to the z -bond 5185.
01:03
And then the next time we will need to compare the test statistics.
01:07
The formula will be the z equal to the p minus p over the square of the b times 1 minus b over the n.
01:15
So we have the phot equal to the 0 .5185 p equal to the 0 .5 over a square root 0 .5 times 1 minus 0 .5 over the n...
