Do left handed starting pitchers pitch more innings per game on average than right handed starting pitchers? A researcher looked at ten randomly selected left handed starting pitchers' games and eleven randomly selected right handed pitchers' games. The table below shows the results. Left: 7 5 5 7 6 7 5 6 Right: 6 5 4 6 4 5 4 5 5 3 5 Assume that both populations follow a normal distribution. What can be concluded at the the a = 0.01 level of significance level of significance?
