The distribution ages for student at the state college is positively skewed with a mean of µ = 21.5 and a standard deviation Ó = 3.
What it the probability of selecting a random sample n = 4 students with an average age greater than 23? (CAREFUL: This is a trick question)
What is the probability of selecting a random sample of n = 36 students with an average age greater than 23?
For a sample of n = 36 students, what is the probability that the average age is between 21 and 22?
