Solved: The mean water temperature downstream from a power plant cooling tower discharge
Chapter 9, Problem 9-20(choose chapter or problem)
The mean water temperature downstream from a power plant cooling tower discharge pipe should be no more than 100F. Past experience has indicated that the standard deviation of temperature is 2F. The water temperature is measured on nine randomly chosen days, and the average temperature is found to be 98F. (a) Should the water temperature be judged acceptable with 0.05? (b) What is the P-value for this test? (c) What is the probability of accepting the null hypothesis at 0.05 if the water has a true mean temperature of 104 F?
