In a study of facial behavior, people in a control group aretimed for eye contact in a 5-minute period. Their times arenormally distributed with a mean of 181.0 seconds and a standarddeviation of 54.0 seconds. Use the 68-95-99.7 rule to find theindicated quantity. a. Find the percentage of times within 54.0seconds of the mean of 181.0 seconds. % (Round to one decimal placeas needed.) b. Find the percentage of times within 108.0 seconds ofthe mean of 181.0 seconds. % (Round to one decimal place asneeded.) c. Find the percentage of times within 162.0 seconds ofthe mean of 181.0 seconds. % (Round to one decimal place asneeded.) d. Find the percentage of times between 181.0 seconds and289 seconds. % (Round to one decimal place as needed.)
