The following times were recorded by the quarter-mile and mile runners of a university track team (times are in minutes) Quarter-Mile times 0.93 0.98 1.05 0.90 0.99 Mile times 4.42 4.45 4.70 4.60 4.60 After viewing this sample of running times, one of the coaches commented that the quarter-milers turned in the more consistent times. Use the standard deviation and the coefficient of variation to summarize the variability in the data. Compute the sample standard deviation (in min) for quarter-mile runners and one-mile runners. (Round your answers to four decimal places.) quarter-mile runners min one-mile runners min Compute the coefficient of variation for quarter-mile runners and one-mile runners. (Round your answers to one decimal place.) quarter-mile runners one-mile runners Does the use of the coeficient of variation indicate that the coach's statement should be qualified?
