Ten percent of the experimental subjects have startle responses above what value?Ĭasino gaming yields over $35 billion in revenue each year in the United States. Give an interval for x centered around 37.9 milliseconds so that the probability that x falls in the interval is. ![]() Find the probability that x is less than 30 milliseconds. Find the probability that x is between 40 and 50 milliseconds. Assume that the startle response x for a person with the specified blood alcohol level is approximately normally distributed. The mean and standard deviation of the startle responses were 37.9 and 12.4, respectively. Using sophisticated equipment to monitor the subjects’ eye movements, the psychologists recorded the startle response (measured in milliseconds) of each subject. After obtaining a specified blood alcohol level, the psychologists placed experimental subjects in a room and threatened them with electric shocks. A group of Florida State University psychologists examined the effects of alcohol on the reactions of people to a threat (Journal of Abnormal Psychology, Vol. ![]()
