2. The Wisconsin State Court system wants to assess the impact that punitive damages have on large tort awards. Using the court system’s computer, 16 cases were selected at random from all those cases in which damages of $1 million or more were awarded. The sample revealed the following about the punitive damages in these cases:
Mean= $74,000 standard deviation= $55,000
Place a 99% confidence limit around your best estimate of the punitive damages for this type of case. One concern is that punitive damages for these cases might be in excess of $100,000. Present a hypothesis and a null hypothesis and evaluate your hypotheses. Finish with a conclusion that a judge could understand.
3. After a massive inventory, Central Library finds 12% of its volumes missing. As a result, Central institutes new procedures to prevent theft. After instituting these procedures for 1 year, Central Library wants to know whether they are working, but it cannot afford the cost of a complete inventory. The library takes a sample of 200 books and cannot locate 14 of them. These 14 are assumed to be lost to theft. What can you say about the new procedures?
4. If the error rate for TANF (Temporary Assistance for Needy Families) payments is greater than 5%, the federal government will cut off funding to the state of Utah. To see whether this is a problem, the agency director takes a sample of 250 TANF recipients and finds that errors have been made in 18 cases. What is your best estimate of the error rate in Utah? Place a 90% confidence limit around this estimate. Present a hypothesis and a null hypothesis and evaluate them. State a conclusion in plain English.
