The Central Limit Theorem states that as n becomes large, the distnbution of Z+(Xˉ−X)/σXˉ approaches the standard normal distribution. True False: QUESTION 4 The central imit thoorom ensures that the sampling distribution of the sample mean Xˉ approaches the normal cistribution as the sample size n increases. True False QUESTION 5 If the standard error of the sampling distribution of sample proportions is 0.0245 for samples of size 400 , then the population proportion must be 0.40 . True Faise QUESTION 6 If the population distribution is unknown, the sampling distribution of the sample mean Xˉ in most cases, can be approximated by the normal distribution if the samp size is large. True False QUESTION 7 Whon a groat many simple random samples of size n are drawn from a population that is normally distributed, the sampling distribution of the sample means will be normal regardless of sample size n. True False QUESTION 8 Statisticians and decision makers usualy use the population mean to estimate the sample mean. True False
