The mean construction time for a standard two car garage by Arrowhead Construction Company is 3.5 days. The time for the construction process follows the normal distribution. The construction process is modified through the use of a "quick setting concrete" for the foundation and floor. This should allow the next phase of construction to start in a timely manner. A sample of 12 garages had a mean construction time of 3.0 days with a standard deviation of 0.9 days.
