Question
Does the location of your seat in a classroom play a role in attendance or grade? 800 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). Use the Tech Help button for further assistance. The number of students who attended in the second group was 154. The number of students who attended in the third group was 150. The number of students who attended in the fourth group was 150. What are the hypotheses? H_0: The average attendance in each group is different from the average attendance for the class. H_1: The average attendance in each group is the same as the average attendance for the class. H_0: The average attendance in each group is the same as the average attendance for the class. H_1: The average attendance in each group is different from the average attendance for the class. None of these. Compute the P-value. P-value = (Round to three decimal places as needed.)Explanation / Answer
Answer:
Attendance for the first group= 800-(154+150+150) =346
