In the past, a medical clinic found that 40% of its patients had illnesses of a psychosomatic nature. A psychologist employed by the clinic wants to see if the percentage has decreased. To see if there is support for a decrease in the 40% figure, the psychologist examines the records of a random sample of 80 of the clinic's patients and finds that 20 have illnesses of a psychosomatic nature. Based on the sample results, would you conclude that the 40% figure has decreased? Use a = .10.
