In a 5-minute period the number of seconds of eye contact between humans is normally distributed with a mean of 184.0 seconds and a standard deviation of 55.0 seconds. What number of seconds corresponds to the shortest 8% of eye contact measurements?
Are you calculating the top or bottom 8%
So, which percentage needs to be converted to an area?
What is the area that you will look for in the table (four decimal places)?
What area will you actually use from the table (four decimal places)?
What is the z-score associated with that area (two decimal places)?
What number of seconds corresponds to the shortest 8% of eye contact measurements? (Round to the nearest whole number)
Are values lower or higher than that value also in the shortest 8%?
