Question

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\,\text{mL}275mL275, start text, m, L, end text and standard deviation of 10\,\text{mL}10mL10, start text, m, L, end text. Suppose that we take random samples of 555 of these drinks and calculate the mean amount of liquid \bar x
