Extracted text: 1. A manufacturer of sprinkler systems designed for fire protection claims that the average activating temperature is at least 135 F. To test this claim, you randomly select a sample of 32 systems and find the mean activation temperature to be 133F. Assume the population standard deviation is 3.3F. At a-0.10, do you have enough evidence to reject the manufacturers claim?
