The Central Limit Theorem says that, if the sample size n exceeds 30, then it must be the case that the population will follow a normal distribution. Not yet Private filesExplanation / Answer
1) True
The sample mean is a random variable that is an estimator of the population mean. The expected value of the sample mean is equal to the population mean µ. Therefore, the sample mean is an unbiased estimator of the population mean.
2) option b) Collapse on the true parameter 'u'as the sample size increases
3) option c)the distribution of Sample mean is approximately normal for a large n
4)True
