On a test of motor coordination, the population of average bowlers has a mean score of 24, with a standard deviation of 6. A random sample of 30 bowlers at Bubba’s Bowling Alley has a sample mean of 26. A second random sample of 30 bowlers, at Babette’s Bowling Alley, has a mean of 18. Using the .05 criterion and both tails of the sampling distribution, decide if each sample represents the population of average bowlers.
