Chapter 23 -
A real estate office wants to make a survey in a certain town, which has 50,000 households, to determine how far the head of household has to commute to work. A simple random sample of 1,000 households is chosen, the occupants are interviewed, and it is found that on average, the heads of the sample households commuted 8.7 miles to work; the SD of the distances was 9.0 miles. (All distances are one-way; if someone is not working, the commute distance is defined to be 0.)
A) The average commute distance of all 50,000 heads of households in the town is estimated as ____________, and this estimate is likely to be off by __________ or so.
B) If possible, find a 95% confidence interval for the average commute distance of all heads of households in the town. If this is not possible, explain why not.
