University dining services wants to know how satisfied students are with the robotic service. It surveyed 60 students on campus and asked them to rate the service on a 100 point scale. They obtained a sample average of 82 points. This service has been provided by the University for some time and the population standard deviation of satisfaction is known to be 8 points.  a) What is the population for which inferencing is being done? [narrative, no calculation] b) What is the population parameter for which inferencing is being done? [narrative, no calculation] c) At a 96% level of confidence, what is the margin of error?
