Do left handed starting pitchers pitch fewer innings per game on average than right handed starting pitchers A researcher looked at nine randomly selected left handed starting pitchers games and nine randomly selected right handed pitchers games The table below shows the results Left 7 6 7 6 6 66 67 Right 78 6 8 7 6 7 7 6 Assume that both populations follow a normal distribution What can be concluded at the the a 0 01 level of significance level of significance For this study we should use Select an answer a The null and alternative hypotheses would be Ho Select an answer H Select an answer Select an answer Select an answer Select an answer Select an answer please enter a decimal Please enter a decimal b The test statistic c The p value d The p value is a e Based on this we should Select an answer the null hypothesis f Thus the final conclusion is that please show your answer to 3 decimal places Please show your answer to 4 decimal places The results are statistically insignificant at a 0 01 so there is insufficient evidence to conclude that the population mean innings per game for left handed starting pitchers is less than the population mean innings per game for right handed starting pitchers The results are statistically insignificant at a 0 01 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 a 0 01 so there is sufficient evidence to conclude that the population mean innings per game for left handed starting pitchers is less than the population mean innings per game for right handed starting pitchers The results are statistically significant at a 0 01 so there is sufficient evidence to conclude that the mean innings per game for the nine left handed starting pitchers that were looked at is less than the mean innings per game for the nine right handed starting pitchers that were looked at
