Pharmaceutical companies promote their prescription drugs using television advertising. In a survey of 120 randomly sampled television viewers, 12 indicated that they asked their physician about using a prescription drug they saw advertised on TV.
Develop a 90% confidence interval for the proportion of viewers who discussed a drug seen on TV with their physician. (Round your answers to 3 decimal places.)
Is it reasonable to conclude that 24% of the viewers discuss an advertised drug with their physician?
