1. Construct a 95% confidence interval for the population proportion of New York residents who disapproved of the Workers. Also calculate the margin of error?
2. Now construct a 99% confidence interval for the above scenario. Describe the differences that you see between the confidence interval you calculated in Part (1) and this one.
3. Show the implications of the differences between these 2 confidence intervals
