Suppose an advertising agency believes that the proportion of children prefer summer over all other seasons is higher than 50%. To test this, 100 children are surveyed, and 64 say that summer is their favorite season. If we use significance level α = 0.05, what is the conclusion of this test?
Note: this is a one-side test, since we are testing whether µ > 0.5 or µ ≤ 0.5.

Suppose that we wish to assess whether more than 60 percent of all U.S. households in a particular income class bought life insurance last year. That is, we wish to assess whether p, the proportion of all U.S. households in the income class that bought life insurance last year, exceeds .60. Assume that an insurance survey is based on 1,000 randomly selected U.S. households in the income class and that 640 of these households bought life insurance last year. a) Assuming...

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 31 vehicles owned by residents of Chicago showed
that the average mileage driven last year was 10.8 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.
