The vice president of programming at NBC is finalizing the prime-time schedule for the fall. She has decided to include a hospital drama but is unsure which of two possibilities to select. She has a pilot called The Surgeon and another called Critical Care. To help her make a final decision, a sample of 20 viewers from throughout the United States was asked to watch the two pilots and indicate which show they prefer. The results were that 12 liked The Surgeon, 7 liked Critical Care, and one had no preference. Is there a preference for one of the two shows? Use the .10 significance level.
