<PRE><B>Question 1130759</B>
The mean of the times it takes a commuter to get to work in Baltimore is 29.7 minutes. If the standard deviation is 6 minutes, within what limits would you expect approximately 68% of the times to fall? Assume the distribution is approximately bell-shaped. 
Note:: 68% of the population is within one standard deviation of the mean.

Answer::
Lower limit:: 29.7-6 = 23.7 minutes
Upper limit:: 29.7+6 = 26.7 minutes
