# The mean water temperature downstream from a power plant cooling tower discharge pipe should be no more than 95of. past experience has indicated that the standard deviation of temperature is 2of. the water temperature is measured on 9 randomly chosen days, and the average temperature is found to be 93of. round your answers to four decimal places (e. g. 98.7654). (a) is there evidence that the water temperature is acceptable at alpha equals 0.05? the water temperature significantly greater than 95of at alpha equals 0.05. (b) what is the p-value for this test? p-value = (c) what is the probability of accepting the null hypothesis at alpha equals 0.05 if the water has a true mean temperature of 99of?
