- A vote is to be taken among the residents of a town and the surrounding county to determine whether a proposed chemical plant should be constructed. The construction site is within the town limits, and for this reason many voters in the county believe that the proposal will pass because of the large proportion of town voters who favor the construction. To determine if there is a significant difference in the proportions of town voters and county voters favoring the proposal, a poll is taken. If 120 out of 200 town voters favor the proposal and 240 out of 500 county voters favor it, would you agree that the proportion of town voters favoring the proposal is higher than the proportion of county voters? Use an alpha = 0.01 level of significance.arrow_forwardA winter resort took a poll of its 350 visitors to see which winter activities people enjoyed.

Forty law students volunteered for the study and provided informed consent. All of the participants observed a videotape of a crime.
