1. Artificial trees? An association of Christmas tree growers in Indiana wants to know if there is a difference in preference for natural trees between urban and rural households. The association sponsored a survey of Indiana households that had a Christmas tree last year to find out. In a random sample of 160 rural households, 46% had a natural tree. In a random sample of 261 urban homes, 34% had a natural tree. Test the appropriate hypothesis.
