Question

central limit theorem help

Answer 1

Currently, quarters have weights that are normally distributed with a mean of 5.670 g and a standard deviation of 0.062 g. A vending machine is configured to accept only those quarters with weights between 5.550 g and 5.790 g. If 280 different quarters are inserted into the vending machine, what is the probability that the mean falls between the limits of 5.550 g and 5.790g?

Answer 2

this is not a central limit problem. Your underlying distribution is already normal

Answer 3

its the lesson im taking i dont know how to solve this problem
