Of 164 Chattanooga residents surveyed, 57 indicated that they participated in a recycling program. In Knoxville, 130 residents were surveyed and 40 claimed to recycle, (a) Determine a 95% confidence interval estimate for the difference between the proportion of residents recycling in the two cities. (Use Chattanooga - Knoxville. Round your answer to three decimal places.) to (b) From your answer in part (a), is there sufficient evidence to conclude that there Is a significant difference in the population proportion of residents participating In the recycling program? Because the range of the interval is from positive to positive, it indicates that there is conclusive evidence (at 95% confidence) that the proportion of Chattanooga residents that recycle is significantly more than Knoxville residents. Because the range of the Interval is from negative to positive, It Indicates that there is no conclusive evidence (at 95% confidence) that the proportion of Chattanooga residents that recycle is significantly different from Knoxville residents. Because the range of the interval is from negative to positive, it indicates that there is conclusive evidence (at 95% confidence) that the proportion of Chattanooga residents that recycle is significantly different from Knoxville residents.
