Sometimes polls provide important information on topics that seem to be outside their scope. The New York Times conducted a survey to determine voter preferences in the 1992 presidential election. A total of 2,374 telephone interviews were conducted with adult U.S. citizens, excluding Alaska and Hawaii. 1912 citizens indicated that they had voter registration. The sample of telephone numbers was obtained by computer from a list of telephone exchanges in the country. In the case of each telephone exchange, the telephone numbers were formed by randomly choosing 6 digits (Random), thus having access to the numbers that appeared on the list and those that did not appear. With the above data, generate a 99% confidence interval for the proportion of adult citizens living in the continental United States who had voter registration in 1992.
