- BMX racing is a sprint sport where races range from around 30 to 45 seconds depending on thelength of the track. Given races are over in such a short time, the start - commonly referred to asgate starts due to everyone lining up on a gate, are critical to success in the sport. A coach with aparticular interest in data analysis coaching an elite athlete records data at a local race track for thetime it takes their athlete to reach the bottom of the starting hill.The coach has found that the hill times for their athlete follow a normal distribution with mean 2.3seconds and standard deviation 0.02 seconds. (a) What hill time distinguishes the slowest 10% of hill times? (b) What is the probability that a randomly selected hill time is less than 2.27 seconds? (c) Let X be the number of hill times that are less than 2.27 seconds from 10 separate starts. Assuming the athlete is well rested between starts, what distribution might you consider X to follow.

Determine which supermarket has a greater variability of its profits.16 In 1970, the U.S. Armed Services instituted a lottery as a random selection process when 19- year old males were drafted into service. Each of the possible 366 possible birth dates was placed in a separate capsule and each capsule was placed in a large plastic drum. Those with the lowest lottery numbers were drafted before others. For example, the May 9th was 176. This meant that there would be 175 groups of males born on other days drafted before those who had been born on May 9th. The scatter plot below shows the median draft eligible number for each month of the year. The line that connects the points is sometimes called a median trace line. Which one of the following statement is TRUE? * Median Trace of Draft Lottery Numbers 240 220- 200- 180- 160 140 120 100 F M. A Median Draft Number to
