19. Eye Contact In a study of facial behavior, people in a control group are timed for eye contact in a 5-minute period. Their times are normally distributed with a mean of 184.0 s and a standard deviation of 55.0 s (based on data from “Ethological Study of Facial Behavior in Nonparanoid and Paranoid Schizophrenic Patients,” by Pittman, Olk, Orr, and Singh, Psychiatry, Vol. 144, No. 1). For a randomly selected person from the control group, find the probability that the eye contact time is greater than 230.0 s, which is the mean for paranoid schizophrenics.
