19) A statistics student wants to determine if a quiet room is a better study environment for students than a noisy environment. 75 students were randomly assigned to a quiet study environment while the other 76 were assigned to a noisy environment. Students in each group were given a short booklet from which to study and then were given a brief multiple-choice test. 64 of the students who studied in the quiet study environment passed the test, compared to 59 students who were in the noisy environment, Let p = the true proportion of all students like these who study in a quiet environment and pass the test and po = the true proportion of all students like these who study in a noisy environment and pass the test. The student wanted to conduct a significance test of p - py . What is the test statistic and p-value? Oz=-0.797 & p-value = 0.916 Oz = 1.22 & p-value = 0.084 Oz =-1.09 & p-value = 0.1789 O z = 1.09 & p-value = 0.1379
