To test whether the more expensive bats do increase the average distance hit, ten little league batters of the same age were randomly chosen. The batters hit ten balls with the top of the line bat and after a rest; hit ten balls with the lower price bat. The data below represents the dis- tance hit in feet for the batters. At the 5% significance level, does the evidence suggest that the top of the line bat does increase the average distance hit versus the lower price bat?
