**Dr. Jane**, Tuesday, March 5, 2013 at 8:49amYou have to find a z-score.

35-38 divided by 5.

Now, that you have the z-value, use a table or a calculator to find the area under the normal curve to the left of your z-value. This is the probability that it will take him less than 35 minutes to get to work.

This is really a Statistics problem. Make sure your subject line says Statistics and you will get help a little faster.
