A recent Gallup poll of American adults found that 54% of respondents believed that the death penalty is morally acceptable (N=1387). Calculate a 99% confidence interval for this proportion. Be sure to show all relevant intermediate values. Interpret the meaning of this confidence interval.

We provide a sample mean, sample size, population standard deviation, and confidence level. In each case, use the one-mean z-interval procedure to find a confidence interval for the mean of the population from which the sample was drawn. $$\bar{x}=55, n=16, \sigma=5, \text { confidence level }=99 \%$$
