On a standard test of motor coordination a sports psychologist
On a standard test of motor coordination, a sports psychologist found that the population of average bowlers had a mean score of 24, with a standard deviation of 6. She tested a random sample of 30 bowlers at Fred’s Bowling Alley and found a sample mean of 26. A second random sample of 30 bowlers at Ethel’s Bowling Alley had a mean of 18. Using the criterion of p = .05 and both tails of the sampling distribution, what should she conclude about each sample’s representativeness of the population of average bowlers?
