*##ALL PROBABILITIES FOR THIS ASSIGNMENT SHOULD BE CALCULATED WITH THE USE OF EXCEL*** **#FOR TESTING PURPOSES, YOU ARE RESPONSIBLE FOR ALSO KNOWING HOW TO MAKE THESE CALCULATIONS BY HAND*#* The local teachers union has been arguing that the current workload formula does not credit teachers with enough time for mark- ing essay based term papers. As a result a joint council between the union, faculty, and management have set up a task force to determine the time it takes to mark a single student's essay based term paper, with the goal of constructing a new workload for- mula. Based on the sample of marking times collected (below), create a 90% confidence interval for the weight of quarters in circulation.
