What would the null and alternate hypothesis be?
A fire insurance company felt that the mean distance from a home to the nearest fire department in a suburb of Chicago was at least 4.7 miles. It set its fire insurance rates accordingly. Members of the community set out to show that the mean distance was less than 4.7 miles. This, they felt, would convince the insurance company to lower its rates. They randomly identify 64 homes and measured the distance to the nearest fire department for each. The resulting sample mean was 4.4. If σ = 2.4 miles
