On Slide 29 are you sampling with replacement? If so why did you chose to do that? we were confused about how you got a sample mean of eg 1.
Error on Slide 18: graph of question one is wrong, as it displays "a" a being AFTER the mean as well as having an area of 0.75. the working out is correct however.
