- In 2017, the entire fleet of light-duty vehicles sold in the United States by each manufacturer must emit an average of no more than 91 milligrams per mile (mg/mi) of nitrogen oxides (NOX) and nonmethane organic gas (NMOG) over the useful life (150,000 miles of driving) of the vehicle. NOX + NMOG emissions over the useful life for one car model vary Normally with mean 86 mg/mi and standard deviation 5 mg/mi. A company has 36 cars of this model in its fleet. What is the probability that the average NOX + NMOG level of these cars is above 91 mg/mi? (Enter your answer rounded to four decimal places.)arrow_forwardIn 2017, the entire fleet of light-duty vehicles sold in the United States by each manufacturer must emit an average of no more than 91 milligrams per mile (mg/mi) of nitrogen oxides (NOX) and nonmethane organic gas (NMOG) over the useful life (150,000 miles of driving) of the vehicle.

Eden Academy has about 1000 pupils currently enrolled. According to the medical report, the rate at which the P-00 Bomb spreads is proportional to the number of infected persons and to the number of persons not infected. Determine the number of infected pupils after six days if it is reported that after four days, about 50 pupils are already showing symptomps of P-00 Bomb.

Past records indicate that the average shelf life of the mix is 234 days. After a revised mix has been developed, a sample of nine boxes of cake mix gave these shelf lives (in days): 232,238, 238, 239, 236, 243, 243, 244, and 240. At a = 0.05, the manufacturer wants to test if the shelf life of the cake mix increased. What critical value must be used for this test?arrow_forward
