5. The average annual miles driven per vehicle in the United States is 11.1 thousand miles, with a 600 miles. Suppose that a random sample of 26 vehicles owned by residents of Chicago showed that the average mileage driven last year was 10.8 thousand miles. Does this indicate that 6. 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? 1) single proportion ii) single mean (a) What is the level of significance? State the null and alternate hypotheses.
