Question
To study whether the students at a university are more or less satisfied with the current food service compared to the previous food service, a sample of 93 current students is taken and finds that 40 are satisfied with the current food service. A similar survey was taken for the previous food service in which 82 students surveyed found that 41 were satisfied with the previous food service. When testing the hypothesis (at the 5% level of significance) a higher percentage of students were satisfied with the previous food service than with the current food service, what is the test statistic? (please round your answer to 2 decimal places)
