Question:
Mary White (A-15) surveyed physicians to measure their opinions regarding the importance of ethics in medical practice. The measurement tool utilized a scale from 1 to 5 in which a higher value indicated higher opinion of the importance of ethics. The ages and scores of the study subjects are shown in the following table. Can one conclude on the basis of these results that age and ethics score are directly related? Let the probability of committing a type I error be .05. What is the p value?
