Question

I am unsure how to complete this graph, any help would be great, thank you.

Suppose that a committee is studying whether or not there is waste of time in our judicial system. It is interested in the mean amount of time individuals waste at the courthouse waiting to be called for jury duty. The committee randomly surveyed 81 people who recently served as jurors. The sample mean wait time was nine hours with a sample standard deviation of two hours. O Part (a) O Part (b) O Part (c) O Part (d) Construct a 95% confidence interval for the population mean time wasted. (i) State the confidence interval. (Round your answers to two decimal places.) hrs (ii) Sketch the graph. (Round your answers to two decimal places. Enter your a/2 to three decimal places.) CL (iii) Calculate the error bound. (Round your answer to two decimal places.) hrs O Part (e) Explain in a complete sentence what the confidence interval means. O There is a 95% chance that a wait time at the courthouse lies within this interval. O We are 95% confident that the true population mean wait time at the courthouse lies within this interval. O We are 95% confident that a wait time at the courthouse lies within this interval. O We are 95% confident that the mean wait time at the courthouse of the sample of 81 individuals waiting at the courthouse lies within this interval.
