QUESTION 2 A minimum mileage guarantee on the tires of a tire manufacturing company is being considered to be set. When the company conducted many tire tests, it revealed that the mean mileage has a normal distribution with mean 2,752 and standard deviation 119. The tire manufacturer wants to set the minimum guaranteed mileage so that no more than 2.5 percent of tires will have to be exchanged. Calculate the Lower limit of guaranteed mileage? (Round answer to two decimal places ex. 2.09)

Federal officials have investigated the problems associated with disposal of hazardous wastes. One disposal site is the abandoned Stringfellow acid pits in Riverside County, Calif. The EPA sampled water from 12 wells in nearby Glen Avon. The EPA standard for maximum allowable radiation level of drinking water is 13.35 pCi/L. Suppose that the sample of 12 water specimens resulted in a sample mean radiation level of 18.97 pCi/L and a sample standard deviation 6.12. Is this sufficient evidence to indicate that the water in Glen Avon has a mean radiation level that exceeds the EPA standard?. Use t test. (a = 0.05) Ho = 13.35 versus Η μ > 13.35 Let μ denote the true mean radiation level for well water in Glen Avon O Reject Null Hypothesis O Failed to Reject Null Hypothesis
