Mathematics Statistics Standard Deviation
My homework has a list of numbers and I'm working with standard deviation. I know the standard deviation as well as the mean and everything, but it says to find "the weight that is 3 standard deviations below the mean." What is the formula for that, and can I do it on a TI-84+ calculator? Thanks
