Assuming each sample has been randomly drawn from its corresponding population, calculate a 95% condence interval for the proportion of individual: in the paid and unpaid groups who believe further testing of impacts is needed. How would increasing the sample size change your level of condence regardir the sub-population? Explain this result in two sentences and show how you arrived at this conclusion. Calculate 95% confidence intervals for support of unconventional gas development in each subpopulation. Do you think it is likely that the population mean level of support in these two groups is the same? Why or why not? Explai in two sentences. How many individuals in the no payment group would need to be sampled to estimate the population proportion of support for more testing of impacts to within .01
