John drives to work each morning and the trip takes an average of µ = 38 minutes. The

distribution of driving times is approximately normal with a standard deviation of σ = 5

minutes. For a randomly selected morning, what is the probability that John’s drive to

work will take less than 35 minutes?

You 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.
