Q4. 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. The poll results in 120 of 200 town voters favor the proposal and 240 of 500 county residents favor it. Use an α = 0.05 level of significance. (a) State the hypotheses. (b) (c) (d) (2 marks) Compute the proportion of town voters p1, the proportion of country voters p2, and the pooled estimate of proportion p. (7 marks) Compute z-value and its corresponding probability P. (5 marks) State the conclusion whether you would agree that the proportion of town voters favoring the proposal is higher than the proportion of country voters. (6 marks)
