Suppose twenty-two communities have an average of x = 123.6 reported cases oflarceny per year. Assume that o is known to be 36.8 cases per year. Find a 90%, 95%,and 98% confidence interval for the population mean annual number of reportedlarceny cases in such communities. Compare the lengths of the confidence intervals.As the confidence levels increase, do the confidence intervals increase in length?The 90% confidence level has a confidence interval length of 121.1; the 95%confidence level has a confidence interval length of 144.3; and the 98% confidencelevel has a confidence interval length of 171.5. As the confidence level increases,the confidence interval length increases.Correct AnswerThe 90% confidence level has a confidence interval length of 25.8; the 95%confidence level has a confidence interval length of 30.8; and the 98% confidencelevel has a confidence interval length of 36.6. As the confidence level increases, theconfidence interval lengths increases.The 90% confidence level has a confidence interval length of 171.5; the 95%confidence level has a confidence interval length of 144.3; and the 98% confidencelevel has a confidence interval length of 121.1. As the confidence level increases,the confidence interval lengths decreases.The 90% confidence level has a confidence interval length of 7.8; the 95%confidence level has a confidence interval length of 6.6; and the 98% confidencelevel has a confidence interval length of 5.5. As the confidence level increases, theconfidence interval length decreases.You AnsweredThe 90% confidence level has a confidence interval length of 5.5; the 95%confidence level has a confidence interval length of 6.6; and the 98% confidencelevel has a confidence interval length of 7.8. As the confidence level increases, theconfidence interval lengths increases.
