A sports science group claims that due to improved training methods, professional cyclists burn a mean of less than 6000 calories during the annual Monaco Endurance Race. (This would be an improvement on the previously accepted value of 6000 calories.) A study of 20 randomly selected professional cyclists finds that the sample mean number of calories the cyclists burn during the race is 5884 with a sample standard deviation of 765 calories. Assume that the population of numbers of calories burned by professional cyclists during the race is approximately normally distributed. Complete the parts below to perform a hypothesis test to see if there is enough evidence, at the 0.05 level of significance, to support the claim that u, the mean number of calories professional cyclists burn during the Monaco Endurance Race, is less than 6000. (a) State the null hypothesis H, and the alternative hypothesis H, that you would use for the test. Ho: u = 6000 H: µ < 6000 O
