. Suppose that 36 items from a production line are measured. You don’t know the actual shape of the population distribution, but you know that the population mean and standard deviation of the measurements are 50mm and 4mm, respectively. Find the probability that the sample mean of the 36 items will lie between 49 and 51mm.
