Suppose the distance of each jump is a random variable that follows a normal distribution with mean ? and variance ?2. He jumps 8 times and records the following distances. Jump Distance (meters) 1 8.79 2 8.87 3 8.82 4 8.49 5 8.74 6 8.32 7 8.84 8 8.50 Calculate an unbiased estimate for the value of ? Calculate an unbiased estimate for the value of ?2? c. Construct an interval that has a 95% probability of containing ?. The athlete says that he is better than Carl Lewis who jumped an average distance of 8.50 throughout his career. What would you say to that? Suppose both of your guesses from parts a.) and b.) are exactly correct. What is the probability that the athletes next jump is over the world record of 8.95 meters?
