A machine used to fill gallon-sized paint cans is regulated so that the amount of paint dispensed has a mean of 125 ounces and a standard deviation of 0.30 ounce. You randomly select 50 cans and carefully measure the contents. The sample mean of the cans is 124.9 ounces. Does the machine need to be reset? Explain your reasoning. ▼ Yes No , it is ▼ very unlikely likely that you would have randomly sampled 50 cans with a mean equal to 124.9 ounces, because it ▼ lies does not lie within the range of a usual event, namely within ▼ 1 standard deviation 2 standard deviations 3 standard deviations of the mean of the sample means.
