A new virus has taken root in a country. Government officials are reporting that 14.8% of the population is currently infected with the virus. However, epidemiologists across the country claim to be observing a much higher infection rate. It was found that 186 people out of a randomly selected sample of 1100 people from around the country were infected with the virus. Use the critical value method to determine if the sample data support the epidemiologists' supposition that the true rate of infection in the country is higher than 14.8%. Let a = 0.05.
