A Poisson distribution with mean 1.5 represents demand in a single period. A Poissondistribution with what mean should be used to represent demand over three periods?
Water samples are taken from water used for cool- ing as it is being discharged from a power plant into a river. It has been determined that as long as the mean tem- perature of the discharged water is at most 150°F, there will be no negative effects on the river’s ecosystem. To investigate whether the plant is in compliance with regu- lations that prohibit a mean discharge water temperature above 150°F, researchers will take 50 water samples at randomly selected times and record the temperature of each sample. The resulting data will be used to test the hypotheses H0: m = 150°F versus Ha: m > 150°F. In the context of this example, describe Type I and Type II er- rors. Which type of error would you consider more seri- ous? Explain.
