The Central Limit Theorem basically states that the sampling distribution will be normal as long as the subgroup size is large enough.
a)
As the sample size increases, the sampling distribution of the mean, X-bar, can be approximated by a normal distribution with mean µ
the distributions becomes more and more normal
b)
As the sample size increases, the sampling distribution of the mean, X-bar, can be approximated by a normal distribution with
a variance σ2/n where n is sample size
the spread of the distributions decreases

True or False: the central limit theorem states that the sampling distribution of the sample mean is approximately normal whenever the population from which we are sampling is normally distributed Assume that 14% of the items produced in an assembly line operation are defective, but that the firm’s production manager is not aware of this situation. Assume firtber that the wuality assurance department to determine the quality of the assembly operation tests 50 parts. What is the probability that the...

In the notes there is a Central Limit Theorem example in which a sampling distribution of means is created using a for loop, and then this distribution is plotted. This distribution should look approximately like a normal distribution. However, not all statistics have normal sampling distributions. For this problem, you'll create a sampling distribution of standard deviations rather than means. 3. Using a for loop, draw 10,000 samples of size n-30 from a...
