mean water temperature downstream from a discharge pipe at a power plant cooling tower should be no more than 100°F. Past studies has shown that the standard deviation of temperature is 2°F. The water temperature was measured on 10 randomly chosen days, and the results are shown below: 96.15 , 97.81 , 97.09 , 95.0P , 99.46 , 100.03 , 99.74 , 98.85 , 95.08 , 98.71
a. State the null hypothesis and alternative hypothesis for the above problem.
b. Is there evidence that the water temperature is acceptable at α = 1%?
c. Compute the 95% confidence interval for the mean temperature of water.
