Suppose that the managers in the previous problem had decided prior to data collection to only include households that planned to make a furniture purchase in the next six months. A screening question was used to identify households that qualified to complete the survey. Further, the 2,500 elements drawn for the sample were accounted for as follows: 473 completed interviews, 612 not-at-homes, 431 refusals, 222 nonworking telephone numbers, and 762 ineligibles.
