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. Group Attendance 1 2 3 4 0.77 0.75 0.69 0.59 The number of students who attended in the first group was 308 The number of students who attended in the second group was 300 The number of students who attended in the third group was 276 The number of students who attended in the fourth group was 236. What is the test statistic? (Round to three decimal places as needed.)
