Terri Vogel, an amateur motorcycle racer, averages 129.41 seconds per 2.5-mile lap (in a 7 lap race) with a standard deviation of 2.25 seconds. The distribution of her race times is normally distributed. We are interested in one of her randomly selected laps. (Source: logbook of Terri Vogel) Let X be the number of seconds for a randomly selected lap. Round all answers to 4 decimal places where possible. Find the proportion of her laps that are completed between 129.57 and 130.63 seconds. (______)The fastest 3% of laps are under(______) seconds. The middle 40% of her laps are from(_____) seconds to(_______) seconds.
