The mean water temperature downstream from a power plant cooling tower discharge pipe should be no less than 98°F. Past experience has indicated that the standard deviation of temperature is 2.1°F. The water temperature is measured on nine randomly chosen days, and the average temperature is found to be 96°F. Should the water temperature be judged acceptable with 10% level of significance? the complete Test of Hypothesis
