Before a final decision is made, network executives commission a sample of 450 viewers. After viewing the shows, 200 indicated they would watch the new show and suggested it replace the crime investigation show.   Estimate the value of the population proportion. (Round your answers to 3 decimal places.)           Develop a 98% confidence interval for the population proportion. (Use  z Distribution Table.) (Round your answers to 3 decimal places.)
