5. A Colorado judicial committee has been asked to evaluate the efficiency of the judicial system, specifically the amount of time wasted in courthouses while citizens wait to be called for jury duty. The population mean is currently believed to be no more than 3 hours. A random sample of 28 Coloradans produced a mean wait time of 3.4 hours with a standard deviation of 1.1 hours. Is there enough evidence to suggest the mean wait time is more than 3 hours? a. State the null and alternative hypotheses. b. C. Determine the appropriate critical value(s) for a = 0.01. Calculate the test statistic. d. Calculate the corresponding p-value. e. Make a decision and justify your choice.
