Question Help ▼ nstructor-created question 1000 patients are each paired with a patient with similar age and clinical condition, so that there are 500 pairs. One patient within each pair is given Treatment A and the other Treatment B. The results are shown in the following table. B is cured B is not A totals A is cured 400 30 430 A is not 20 50 70 B totals 420 80 500 At the a = 0.01 level of significance, use McNemar's test to: test Ho: Response is independent of treatment. versus Ha: Response depends on treatment. Critical value from chi-square table is: Test statistic is: Does the sample provide sufficient evidence that response depends on treatment? Answer yes or no:

A study was conducted to examine the impact of speaking in public on college students. A class of 15 statistics students participated in the study. At the beginning of a lecture the students recorded their systolic blood pressure. During the lecture the instructor called on each student to stand and answer questions about topics in the lecture. After speaking the students once again recorded their blood pressure. The resulting values are given below along with summary statistics. before 100 123 128 125 136 108 130 113 105 136 146 138 108 149 132 after 141 142 146 136 144 111 132 114 103 133 140 130 100 133 113 difference -41 -19 -18 -11 -8 -3 -2 -1 2 3 6 8 8 16 19 before after difference mean 125.1 127.9 -2.733 st dev 15.26 15.45 15.23 Does this information indicate that blood pressure increased because of speaking?
