Mean and Standard Deviation of the Sampling Distribution
Hi, I'm really having trouble with this math homework! Help please!
A machine automatically dispenses a beverage of a desired size. When set to "small," the machine dispenses varying amounts of liquid with a mean of 275 https://uncc.instructure.com/equatio...xt%257BmL%257DmL and standard deviation of 10 https://uncc.instructure.com/equatio...xt%257BmL%257DmL. Suppose that we take random samples of 5 of these drinks and calculate the mean amount of liquid https://uncc.instructure.com/equatio...%255Cbar%2520xx¯ in each sample. We can assume that individual drinks are independent.
