A trucking company would like to compare two different routes
for efficiency. Truckers are randomly assigned to two different
routes. Twenty truckers following Route A report an average of 47
minutes, with a standard deviation of 5 minutes. Twenty truckers
following Route B report an average of 50 minutes, with a standard
deviation of 3 minutes. Histograms of travel times for the routes
are roughly symmetric and show no outliers. a) Find a 95%
confidence interval for the difference in the commuting time for
the two routes.
