Hi, i'm david and i'm here to have the answer your question.
00:03
Now let me bring up your question here.
00:06
In this question here, we're going to perform the high -bodies testing.
00:11
And here, imagine we have collected a random symbol on the 31 energy, so n equal to the 31.
00:19
And then we have the label clamped and each part contains 20 grams, so mill equal to the 20 here.
00:27
And we will have the symbol mean, xpar equal to the 21 .4, symbol standard diffusion equal to the 2 .54.
00:38
And is it possible for the population mean could be a value other than 20 grams on the protein? this order than here, it will be indicator for us to consider it's a 2 -telt.
00:52
So the answer 22 will be the 2 -telt test because the clam because we want to test the mean is not equal to the 20 grams.
01:21
And now, therefore in the question 23, we will have the known hypothesis at not.
01:28
That the mean will equal to the 20.
01:31
The alternating 1 at 8, mu, will be not equal to the 20.
01:36
And the next one want to state the critical value and add the 0 by 05.
01:42
The critical value here will be the value of the t degree of freedom equal to n minus 1.
01:50
And because it needs a 2 -10, therefore we will have to attend the alpha over 2...
