If the mean (Mu) diastolic blood pressure in a certain age group is 80, and the standard deviation (Sigma) is 10, what is the probability that, in a sample of 100, the sample mean (X) is > 85? You will need to compute standard error to get the answer in the back of the book, which is C = .0003, essentially zero. Standard error = standard deviation divided by the sq root of n.
