A professional baseball player would like to investigate whether the proportion of hits at-bat is different when he bats left-handed and right-handed. To study this further, he randomly samples 120 left-handed bats and 200 right-handed bats from his records. The data from the study are presented in the table below. Let P, be the proportion of hits at-bat when he is batting left-handed and pz be the proportion of hits at-bat when he is batting right-handed. Left-handed bats Right-handed bats Number of hits at-bat 30 48 Sample size 120 200 Assume the conditions for the hypothesis test are satisfied. Is there sufficient evidence at a = 0.01 to show the proportion of hits at-bat is different when he bats left-handed and right-handed? Find the test statistic. Round your answer to the nearest hundredth. Provide your answer below: = test statistica
