If x represents a random variable with mean 131 and standard deviation 40, then the standard deviation of the sampling distribution of the means with sample size 100 is 4. O True O False
You are interested in estimating the mean of a population. You plan to take a random sample from the population and use the sample’s mean as an estimate of the population mean. Assuming that the population from which you select your sample is normal, which of the statements about M are true? Check all that apply. You can only assume that the sampling distribution of M is normally distributed for sufficiently large sample sizes. You can assume that the sampling distribution of M is normally distributed for any sample size. The standard deviation of the sampling distribution of M is equal to the standard deviation of the population divided by the square root of the sample size. The expected value of the sampling distribution of M is equal to the value of the population mean divided by the sample size.
