Is the average time to complete an obstacle course different when a patch is placed over the right eye than when a patch is placed over the left eye? Eight 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. Assume 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 [Select an answer a. The null and alternative hypotheses would be: Ho: Select an answer H₁: Select an answer b. The test statistic c. The p-value- d. The p-value is 2 a e. Based on this, we should [Select an answer the null hypothesis. f. Thus, the final conclusion is that... Time to Complete the Course Right 48 40 50 50 43 45 47 46 Left 52 41 48 53 44 48 49 51 ? Select an answer v ? V - Points possible. 13 This is attempt 1 of 4 Select an answer (please show your answer to 3 decimal places); (Please show your answer to 4 decimal places) O The results are statistically insignificant at o-0.10, 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. O The results are statistically insignificant at o-0.10, 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 not the same as the population mean time to complete the obstacle course with a patch over the left eye The results are statistically significant at a-0.10, 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 not the same as the population mean time to complete the obstacle course with a patch over the left eye The results are statistically significant at -0.10, so there is sufficient evidence to conclude that the eight volunteers that were completed the course in the same amount of time on average with the patch over the night eye compared to the left eye
mathas/assessment/showtest.php?action=skip&to=3 Print Version The director of student services at Oxnard College is interested in whether women are just as likely to attend orientation as men before they begin their coursework. A random sample of freshmen at Oxnard College were asked what their gender is and whether they attended orientation. The results of the survey are shown below: Data for Gender vs. Orientation Ho: Select an answer Hy elect an answer Attendance Women Men Yes 382 No 274 What can be concluded at the a-0.10 level of significance? For this study, we should use Select an answer a. The sull and alternative hypotheses would be: 354 306 Select an answer V b. The test statistic - c. The p-value- d. The p-value is 70 e Based on this, we should [Select an answer the call hypothesis f. Thus, the final conclusion is that. (please show your answer to 3 decimal places) (Please show your answer to 4 decimal places) O The results are statistically insignificant at a-0.10, so there is statistically significant evidence to conclude that the population proportion of freshmen women at Oxnard College who attend t orientation is the same as the population proportion of freshmen men at Oxnard College who attend orientation The results are statistically significant at a-0.10, so there is insufficient evidence to conclude that the population proportion of freshes womes at Oxoard College who attend oritation is different from the population proportion of freshmen men at Osnard College who attend orientation The results are statistically significant at 0.10, so there is sufficient evidence to conclude that the population proportion of freshmen women at Oxnard College who attend orientation is different from the population proportion of fresh men at Oxnard College who attendocientation The results are statistically significant ato-0.10, so there is sufficient evidence to conclude that the proportion of the 656 freshen women who attended orientation is different from the proportion of the 660 freshen men who attended orientation
