Chapter 10.2, Problem 18E
Water specimens are taken from water used for cooling as it is being discharged from a power plant into a river. It has been determined that as long as the mean temperature 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 regulations that prohibit a mean discharge water temperature above 150°F, temperature will be determined for 50 water specimens at randomly selected times. The resulting data will be used to test the hypotheses H0: μ = 150°F versus Ha: μ > 150°F.
- a. In the context of this example, describe Type I and Type II errors.
- b. Which type of error would you consider more serious? Explain.
