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 ten randomly selected right handed pitchers' games. The table below shows the results. Left: 5 6 7 7 5 6 6 Right: 3 4 4 5 8 5 Assume that both populations follow a normal distribution. What can be concluded at the the a = 0. 10 level of significance level of significance? For this study, we should use t-test for the difference between two independent population means a. The null and alternative hypotheses would be: Ho: H1 VY H2 (please enter a decimal) H1 : 1 VY H2 (Please enter a decimal) b. The test statistic t v v = 1798 x (please show your answer to 3 decimal places. ) c. The p-value = 0.9641 x (Please show your answer to 4 decimal places.) d. The p-value is s v v a e. Based on this, we should reject vy the null hypothesis. f. Thus, the final conclusion is that ... The results are statistically insignificant at o = 0. 10, so there is statistically significant evidence to conclude that the population mean innings per game for left handed starting pitchers is equal to the population mean innings per game for right handed starting pitchers. The results are statistically significant at o = 0.10, so there is sufficient evidence to conclude that the mean innings per game for the ten left handed starting pitchers that were looked at is more than the mean innings per game for the ten right handed starting pitchers that were looked at. The results are statistically significant at o = 0.10, so there is sufficient evidence to conclude that the population mean innings per game for left handed starting pitchers is more than the population mean innings per game for right handed starting pitchers. The results are statistically insignificant at a = 0.10, so there is insufficient evidence to
