Question: The Prescott Rural Electric Company operates a nuclear power plant on the Prescott River, just south of town. At this plant the Coop uses river water to cool the heat exchangers. The Environmental Protection Agency (EPA) has a rule that power plants can use river water to cool heat exchangers so long as the discharged water is on average no more than 140 degrees . To determine if the Coop’s discharged water is in compliance the EPA took 85 different water samples over a three week period. They found that the mean was 143.25 with a standard deviation of 4. 7 degrees . At the .05 level of significance write the null and research hypotheses and find out if the Coop’s discharged water is in compliance with EPA rules.
