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 wit seconds and a standard deviation of 51.0 seconds. Use the 68-95-997 rule to find the indicated quantity. a. Find the percentage of times within 51.0 seconds of the mean of 185.0 seconds. 68.0 % (Round to one decimal place as needed.) b. Find the percentage of times within 102.0 seconds of the mean of 185.0 seconds. 95 % (Round to one decimal place as needed.) c. Find the percentage of times within 153.0 seconds of the mean of 185.0 seconds [% (Round to one decimal place as needed.)
