A paper suggests that the simple linear regression model is reasonable for describing the relationship between y = eggshell thickness (in micrometers, µm) and x = egg length (mm) for quail eggs. Suppose that the population regression line is y = 0.115 + 0.007x and that σe = 0.005. Then, for a fixed x value, y has a normal distribution with mean 0.115 + 0.007x and standard deviation 0.005. Approximately what proportion of quail eggs of length 14 mm have a shell...
