Does the location of your seat in a classroom play a role in attendance or grade? 1600 students in a physics course were randomly assigned to one of four groups. The 400 students the class, the 400 students in group 2 sat 4 to 6.5 meters from the front, the 400 students in group 3 sat 6.5 to 9 meters from the front, and the 400 students in group 4 sat 9 to 12 meters from the front. Complete parts (a) through (c). group 1 sat 0 to 4 meters from the front of What are the hypotheses? Ho: The average attendance in each group is the same as the average attendance for the class. H,: The average attendance in each group is different from the average attendance for the class. What is the test statistic? Xổ = 0.211 (Round to three decimal places as needed.) What is the range of P-values of the test? The range of P-values of the test is greater than 0.10. Is there a significant difference among the groups in attendance patterns? Recall that a = 0.01. O A. Yes. H, should be rejected because the P-value of the test is greater than a. O B. Yes. Ho should be rejected because the P-value of the test is less than a. C. No. Ho should not be rejected because the P-value of the test is greater than a. O D. No. H, should not be rejected because the P-value of the test is less than a.

O B. Yes. Ho should be rejected because the P-value of the test is less than a.
OC. No. H, should not be rejected because the P-value of the test is greater than a.
O D. No. H, should not be rejected because the P-value of the test is less than a.
(b) For the second half of the semester, the groups were rotated so that group 1 students moved to the back of class and group 4 students moved to the front. The same switch took place between groups 2 and 3. The
attendance for the second half of the semester averaged 70%. The data show the attendance records for the original groups. How many students in each group attended, on average? Is there a significant difference in
attendance patterns? Use the p-value approach and use the level of significance a = 0.01.
