Q: Consider the formula for a Z statistic (Z = [(X - U)/S]. Let's say that the mean age of people in a class of 31 students is 33.8 years, and the standard deviation is equal to 7 years, and that you as a member of the class are 26. Substitute these values into the formula and tell me what Z is equal to? What does this tell us?
