Hello students, let's discuss the question.
00:03
Here it is given population consisting values 1 to 8.
00:09
Now, sample, the samples of size 2 are 1 .2, 1 .8 and 2.
00:36
So here this is one of the answer.
00:45
So population mean is mean of 1 2 8.
01:02
So this gives 3 .67.
01:07
This is also one of the answer.
01:10
Now in the next part, population variance.
01:22
So this is this is variance of 1 2 8.
01:30
So this is equal to 14 .33.
01:37
This is the answer of the next part.
01:40
Now population standard variance.
01:56
So this is square root of 14 .33.
02:04
So this gives 3 .7859.
02:09
This is the next answer.
02:15
Now for the samples, the mean values are 1 .5 comma 4 .5 .5 .5.
03:03
This is the next answer.
03:05
Similarly, mean of sampling distribution of mean is mean of 1 .5 4 .5 and 5.
03:41
So this gives 3 .67.
03:47
Now in the next part, variance of sampling distribution is variance of 1 .5, 4 .5 and 5.
04:20
So this gives us 3 .833.
04:26
This is the next answer.
04:30
Now, standard deviation of sample distribution is, so under root of this value, 3 .5833.
05:02
So we get 1 .890...
