Suppose a sample of O-rings was obtained and the wall thickness (in inches) of each was recorded. Use a normal probability plot to assess whether the sample data could have come from a population that is normally distributed. 0.157, 0.182, 0.206, 0.217, 0.218, 0.236, 0.238, 0.248, 0.257, 0.264,0.275, 0.284, 0.283, 0.303, 0.321, 0.340 Using the correlation coefficient of the normal probability plot, is it reasonable to conclude that the population is normally distributed?
