For many years, TV executives used the guideline that 30% of the audience were watching each of the traditional bi three prime-time networks, and 10% were watching cable stations on a weekday night. A random sample of 500 homes in the Tampa-St. Petersburg area last night showed that 165 homes were tuned into the ABC affiliate, 140 to the CBS affiliate, 125 to the NBC affiliate, and the remainder were viewing a cable station. At the .05 significance level, can we conclude that the national guideline is still reasonable? Show your work.
