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 185.0 seconds and a standard deviation of 51.0 seconds. Use the 68-96-99.7 rule to find the Indicated quantity, a. Find the percentage of times within 51.0 seconds of the mean of 185.0 seconds 68.09% (Round to one decimal place as needed) b. Find the percentage of times within 102.0 seconds of the mean of 185.0 seconds 0% (Round to one decimal place as needed.)
