**11.30 Pollutants in auto exhausts.** The level of nitrogen oxides (NOX) in the exhaust of cars of a particular model varies Normally with a mean of 0.2 grams per mile (g/mi) and a standard deviation of 0.05 g/mi. Government regulations call for NOX emissions no higher than 0.3 g/mi.(a) What is the probability that a single car of this model fails to meet the NOX requirement?(b) A company has 25 cars of this model in its fleet. What is the probability that the average NOX level \(\overline{x}\) of these cars is above the 0.3 g/mi limit?

Given that Mean = 0.2 , Standard deviation = 0.05 , Sample size = 25

The equation for a general normal curve with mean ? and standard deviation ? is images Calculate values for x = 120, 130, ... , 170, 180 where ? = 150 and ? = 30. Note that setting ? = 0 and ? = 1 in this equation gives the equation for the standard normal curve. (Round your answers to four decimal places.)
A person's blood glucose level and diabetes are closely related. Let x be a random variable measured in milligrams of glucose per deciliter (1/10 of a liter) of blood. Suppose that after a 12-hour fast, the random variable x will have a distribution that is approximately normal with mean u = 86 and standard deviation o = 26. Note: After 50 years of age, both the mean and standard deviation tend to increase. For an adult (under 50) after a 12-hour fast, find the following probabilities.

Total plasma volume is important in determining the required plasma component in blood replacement therapy for a person undergoing surgery. Plasma volume is influenced by the overall health and physical activity of an individual. Suppose that a random sample of 50 male firefighters are tested and that they have a plasma volume sample mean of x = 37.5 ml/kg (milliliters plasma per kilogram body weight). Assume that ? = 7.20 ml/kg for the distribution of blood plasma.
A Show Time Remaining A The body lengths of deer mice are known to vary approximately normally, with mean 86 mm and standard deviation 8 mm. A research group is interested whether vitamin supplements will increase deer mouse body length. They select a random sample of 100 deer mice from the population of all deer mice that would ever receive vitamin supplements and observe their body lengths. Suppose the sample mean is calculated as 87.2 mm. Let u be the mean body length of deer mice who receive vitamin supplements. Provide the null and alternative hypotheses most appropriate for this situation. O A. Ho: H = 86 vs. Ha: P> 86 B. Họ: H = 87.2 vs. Hạ: µ 87.2 Reset Selection
