The average mpg (miles per gal) of a new model of motorcycle is known to be normally distributed with mean μ = 27.4 mpg and standard deviation σ = 2.9 mpg. (a) Draw a normal curve with the parameters labeled. (b) Shade the region that represents the proportion of mpgs between 29.3 and 23.7. (c) Suppose the area under the normal curve to between X = 29.3 and X = 23.7 is 0.6419. Provide two interpretations of this result.

    The average annual miles driven per vehicle in the United States is 11.1 thousand miles, with σ ≈ 600 miles. Suppose that a random sample of 41 vehicles owned by residents of Chicago showed that the average mileage driven last year was 10.9 thousand miles. Does this indicate that the average miles driven per vehicle in Chicago is different from (higher or lower than) the national average? Use a 0.05 level of significance. What are we testing in this problem?...
