The National Center for Education Statistics surveyed 4400 college graduates about the lengths of time required to earn their bachelor's degrees. The mean was 5.15 years and the standard deviation was 1.68 years. Based on the above information, find the margin of error for a 98% confidence level. Round your answer to the nearest hundredth.
Answers: 2
level, that is the subtraction of 1 by the confidence interval divided by 2. So:
.
, so 
is the standard deviation of the population and n is the size of the sample.
