You take all possible samples of size 100 from a very large population of values. The mean of the population is 550. The standard deviation is 50. You compute the mean of each sample. 95% of the sample means will be greater than__

Use the Central Limit Theorem to find the mean and standard error of the mean of the sampling distribution. Then sketch a graph of the sampling distribution. The mean price of photo printers on a website is $234 with a standard deviation of $57. Random samples of size 26 are drawn from this population and the mean of each sample is determined. The mean of the distribution of sample means is example Get more help. Clear all Final check
