The probability that a sample of size n will have a mean,
, less that a given value, X, where the population mean,
, and the population standard deviation,
, is known is given by:
Therefore, the required probability is given by:
Idk i think you multiply 45 x 11 but im not smart and im pretty sure i havent learned this yet so dont trust me lol
