An insurance company proposes two health insurance plans for the employees of a company. Plan A is the basic plan and covers only the medication expenses in case of hospitalization, whereas Plan B reimburses all medical expenses of the employees. As a human ressources manager, you are required to estimate how many employees will opt for Plan B. The manager randomly asks 80 emplyees and 17 of them prefer Plan B. Find the upper confidence limite (UCL) of the 98% confidence interval estimate for the population proportion of employees who will prefer Plan B. Round your answer to three decimal places.
