The carbon monoxide emission level for a certain type of vehicle varies normally with a mean of 2.9 grams per mile and a standard deviation of 0.4 gram per mile.
- Calculate the probability that a randomly selected vehicle of this type has an emission level of at least 3.2 grams per mile. For full credit, your answer must have a sketch with labeled parameters, correct boundaries, appropriate shading, and a correct probability.
- Suppose 12 vehicles of this type are randomly selected. Calculate the probability that the sample mean emission level is at least 3.2 grams per mile. For full credit, your answer must have a sketch with labeled parameters, correct boundaries, appropriate shading, and a correct probability.

7. The weights of a certain brand of candies are normally distributed with a mean weight of 0.8551 g and a standard deviation of 0.0521 g. A sample of these candies came from a package containing 446 candies, and the package label stated that the net weight is 380.7 g. (If every package has 446 candies, the mean weight of the candies must exceed 308.7/446 = 0.8536 g for the net contents to weigh at least 380.7 g.) b. If...

For healthy individuals the level of prothrombin in the blood is approximately normally distributed with mean...
For healthy individuals the level of prothrombin in the blood is approximately normally distributed with mean 20 mg/100 mL and standard deviation 4 mg/100mL. Low levels indicate low clotting ability. In studying the effect of gallstones on prothrombin, the level of each patient in a sample is measured to see if there is a deficiency. Let µ be the true average level of prothrombin for gallstone patients. a) What are the appropriate null and alternative hypothesis? b.) Let Xbar denote...
