Question 1. Suppose that a committee is studying whether or not there is waste of time in our judicial system. It is interested in the average amount of time individuals waste at the courthouse waiting to be called for service. The committee randomly surveyed 81 people. The sample average was 8 hours with a sample standard deviation of 4 hours. (a) Construct a 95% confidence interval for the population average time wasted and write the interpretation (Sketch the graph). (b) Which distribution you used for this problem? Explain your choice.
