Is the probability distribution of that statistic if sample mean. Value of the statistic that we see in a single valve sampled from that statistic. "s sampling distribution all statistics have sampling distributions. Mean mean ( ne ) , standard deviation ( ox ) I be the sample mean of these n independent observations. Nf the mean of the sampling distribution of. Is equal to the mean of the distribution from which we are sampling ) . ox. Std deviation of the distribution from which we are sampling , divided by the square root of the sample size. Nn has the std normal distribution z= io relating to a single observation. It is well known that fast food tends to be high in sodium.
