The 200 students in a statistics class were randomly divided into two groups of 100 students. both groups were given the same midterm exam at the same time. one group took the exam in a classroom in which the air temperature was normal (68°). the other group was given the exam in a similar room in which the air temperature was unusually warm (84°). both groups had one hour to complete the exam. seventy-four of those taking the exam in the normal room passed, while only 66 of those taking the exam in the warm room passed. let p1 and p2 represent the probability of passing under normal and warm conditions, respectively. to determine if this is evidence that students perform worse under uncomfortable conditions, you test h0: p1 = p2, ha: p1 > p2. the p-value of this test is
a. 0.0547.
b. 0.0618.
