Is the average time to complete an obstacle course when a patch is placed over the left eye Thirteen randomly selected volunteers first completed an obstacle course with a patch over one eye and then completed an equally difficult obstacle course with a patch over the other eye The completion times are shown below Left means the patch was placed over the left eye and Right means the patch was placed over the right eye Time to Complete the Course Right 43 41 40 46 42 40 49 50 Left 44 44 40 49 43 40 48 53 Assume a Normal distribution What can be concluded at the the a 0 05 level of significance level of significance For this study we should use Select an answer a The null and alternative Ho Select an answer H Select an answer hypotheses would be Select an answer Select an answer C please enter a decimal Select an answer Please enter a decimal Select an answer 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 05 so there is insufficient evidence to conclude that the population mean time to complete the obstacle course with a patch over the right eye is less than the population mean time to complete the obstacle course with a patch over the left eye The results are statistically significant at a 0 05 so there is sufficient evidence to conclude that the population mean time to complete the obstacle course with a patch over the right eye is less than the population mean time to complete the obstacle course with a patch over the left eye The results are statistically significant at a 0 05 so there is sufficient evidence to conclude that the eight volunteers that were completed the course faster on average with the patch over the right eye compared to the left eye The results are statistically insignificant at a 0 05 so there is statistically significant evidence to conclude that the population mean time to complete the obstacle course with a patch over the right eye is equal to the population mean time to complete the obstacle course with a patch over the left eye
