Please explain test statistics steps

Does the location of your seat in a classroom play a role in attendance or grade? 500 students in a physics course were randomly assigned to one of four groups. The 200 students in group 1 sat 0 to 4 meters from the front of the class, the 200 students in group 2 sat 4 to 6.5 meters from the front. the 200 students in group 3 sat 6.5 to 9 meters from the front. and the 200 students in group 4 sat 9 to 12 meters from the front. Complete parts (a) through (c). 5 Click the icon to view the chi-square table of critical values. (a) For the rst 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 studens 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 signicant difference among the groups in attendance patterns? Group 1 2 3 4 la Attendance 0.77 0.77 0.75 0.75 The number of students who attended in the rst group was 154 . The number of students who attended in the second group was 154 . The number of students who attended in the third group was 150 r The number of students who attended in the fourth group was 150 . What are the hypotheses? H0: The average attendance in each group is the same as the average attendance for the class H1 : The average attendance in each group is different from the average attendance for the class. What is the test statistic? X3 = (Round to three decimal places as needed.)
