Is there a significant difference among the groups in attendance patterns? Recall that a = 0.01 OA. Yes. Ho should be rejected because the value of the test is greater than a OB. No He should not be rejected because the P-value of the test is less than a OC. Na Ho should not be rejected because the P-value of the test is greater than a OD. Yes Ho should be rejected because the P-value of the test is less than a (b) For the second half of the semester, the groups were totated 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 value approach and use the level of significance 0.01 Group 1 2 3 Attendance 0.77 075069 059 The number of students who attended in the first group was 1 The number of students who attended in the second group was The number of students who attended in the third group was The number of students who attended in the fourth group was What is the test statistic? 73 (Round to these decimal places as needed)
What is the range of P-values of the test? The range of P values of the test is Is there a sigruficant difference in attendance patters? Recall that a= 0.01 O A. No, because the P-value of the test is less than the level of significance, OB. Yes, because the P-vatue of the test is less than the level of sigruficance. Of Yes, because the P-value of the test is greater than the level of significance OD. No, because the value of the test is greater than the level ot significance (c) At the end of the semester, the proportion of students in the top 20% of the class was determined. Of the students in group 1, 28% were in the top 20% of the students in group 2, 22% were in the top 20% of the students in group 3, 19% were in the top 20% of the students in group 4. 11% were in the top 20% How many students would we expect to be in the top 20% of the class il sent location plays no role in grades? The number of students expected to be in the top 20% of the class in group 1 it seat location plays no role ons grades is The number of students expected to be in the top 20% of the class in group 2 is The number of students expected to be in the top 20% of the class in group 3 8 The number of students expected to be in the top 20% of the class in group 4 is What is the full hypothesis HoThe number of students in the top 20% in each group be the same amongst the groups Hi The number of students in the top 20% in each group be the same amongst the groups
What is the test statistic? x = (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 Is there a significant difference in the number of students in the top 20% of the class by group? Recall that c = 0.01 OA. Yes. Hy should be rejected because the P-value of the test is greater than the level of significance OB, No Ho should not be rejected because the P-value of the test is less than the level of significance OC. No. Ho should not be rejected because the P-value of the test is greater than the level of significance. OD. Yes Hy should be rejected because the P value of the test is less than the level of significance
