A national manufacturer of unattached garages discovered that the distribution of the lengths of time it takes two construction workers to erect the Red Barn model is approximately normally distributed with a mean of 32 hours and a standard deviation of 2 hours. What percent of the garages take between 32 and 34 hours to erect?

  1. 76.71%
  2. None of these answers
  3. 16.29%
  4. 34.13%
  5. 3.14%

Answer(s): D

Explanation:

z = (x-u)/sigma. z1 = 32 - 32/2 = 0 and z2 = 34 - 32/2 = 1. From the z tables, z = 0 and z = 1 are 0 and 0.3413 respectively. Therefore, the area under the curve is 0.3413.
