Round all answers to 4 decimal places where possible and assume a normal distribution. a. What is the distribution of X? X ~ N( b. What is the distribution of a? ~ ~ N( c. What is the distribution of > x? > x - N d. If one randomly selected runner is timed, find the probability that this runner's time will be between 19.8691 and 20.2691 minutes. e.
