The average running pace for a non-smoker who runs at least 3-times a week is 9 minutes with a standard devation of 1.5 minutes. Find the probability that a random sample of 40 non-smoking runners will have a mean running pace less than 8.5 minutes. Hint: Find Z-score for sampling distributions of means, then use Table E. Remember to round to nearest 2 decimal places when referencing Table E for probability. (Provide answer as listed in Table E, ex: 0.9988)
