Now let me pick up your question here.
00:07
In this question we will have multiple choice here.
00:12
Which of the following is incorrect statement? for the number a, the sampling distribution of the sample mean has the mean equal to the population mean.
00:27
Even if the population is not normally distributed, this one will be correct because of the sample mean, even though it's not normally distribution, the e of the x bar, it will always equal to the e of the x and equal to the m.
00:44
And for the question b, the larger the value of the sample size and the closer the standard division of sample mean to the standard division of population.
00:55
This will be false because the standard division resemble mean equal to the sigma of square of n.
01:04
So, it's an increasing and then the standard division that x power goes to the zero, and it's not equal to the standard division of the population.
01:20
Therefore, b will be wrong...
