Question Help * In clinical trials of a medication, 2145 subjects were divided into two groups. The 1570 subjects in group 1 received the medication. The 575 in group 2 received a placebo. Of the 1570 subjects in group 1, 64 experienced dizziness as a side effect. In group 2, 16 experienced dizziness as a side effect. To test whether the proportion experiencing dizziness in group 1 is greater than that in group 2, the researchers entered the data into statistical software and obtained the following results Test at =0.1 Sample 64 1570 16 Sample p Estimate for p(1) p(2):0.012938 0.040764 95% Cl for p(1)-p(2):(-0.003687, 0.029564) 0.02782G Test for p( 1 )-p(2)-0 (vs > 0): z 1.40 P-value = 0.081 575 What conclusion can be drawn at the = 0.1 level of significance? O A. Reject Ho. there is enough evidence to conclude that the proportion experiencing dizziness in group 1 is greater than the proportion experiencing dizziness in B. Do not reject Ho there is not enough evidence to conclude that the proportion experiencing dizziness n group 1 is greater than the proportion expenencing c. Do not re ect Ho there is enough evidence to conclude that he proportion experencang dizziness n gro tis greater han the pop ton ex e enc D. Reject Ho there is not enough evidence to conclude that the proportion experiencing dizziness in group 1 is greater han the proportion experiencing dizziness group 2 dizziness in group 2 dizziness in group 2. in group 2 Click to select your answer
