Adrian hopes that his new training methods have improved his batting average. Before starting his new regimen, he was batting 0.550 in a random sample of 80 at bats. For a random sample of 40 at bats since changing his training techniques, his batting average is 0.725. Determine if there is sufficient evidence to say that his batting average has improved at the 0.01 level of significance. Let the results before starting the new regimen be Population 1 and let the results after the training be Population 2. Step 3 of 3 : Draw a conclusion and interpret the decision.
