(04.06 MC) The 200-meter race times at a state track meet are normally distributed with a mean of 13.56 seconds and a standard deviation of 2.24 seconds. Using the Standard Normal Probabilities table, what is the approximate probability that a runner chosen at random will have a 200-meter time less than 13.5 seconds? (5 points)

A twelve-month old boy was in for his one-year health supervision visit 3 days ago, and he received the MMR and HepB and Hib vaccines at that time. His mother chose not to give the Varivax (chickenpox) vaccine because she wanted him to get the “real thing.” She has since changed her mind and wants to come back for the vaccine as soon as possible. The appropriate timing to give this vaccine is:
