Hi, i'm david and i'm here to have you answered your question.
00:04
Now let me bring up your question here.
00:06
In the question here, when you discuss about the central limit theorem, let me remind you that if we have the n greater equal to the 30, and then the sample mean x -par, it will follow by the normal.
00:21
With the mean, it will equal to the mean in the population, the standard division of x -par, equal to the standard division of the population, different number square end.
00:31
In this question here, we are given that the sample end equal to the 36 and we have the symbol mean is less than the 0 .24 or greater than 0 .026 and then the process will shoot down for adjustment.
00:49
We're given the standard division equal to the 0 .02 and the mean is required to be the 0 .25.
00:58
Now the question asks me to find the probability that the manufacturer line will shut down.
01:05
So means then when you find the x -par, it will be between the 0 .24 and the 0 -12.
01:14
Notice that we see the n equals to 36, so it's greater than 30 already.
01:19
So therefore we are able to turn the x -po and j the z by knowing that it followed by the normal...
