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 in group 1 sat 0 to 4 meters from the fro 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). (a) For the first half of the semester, the attendance for the whole class averaged 76%. So, if there is no effect due to seat location, we would expect 76% of students in each group to attend. The data show the attendance history for each group. How many students in each group attended, on average? Is there a significant difference among the groups in attendance patterns? Group Attendance 1 2 3 4 0.77 0.77 0.75 0.75 The number of students who attended in the first group was 308 The number of students who attended in the second group was 308 . The number of students who attended in the third group was 300 The number of students who attended in the fourth group was 300 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? x = 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
