If the acceptable roughness parameter variability is 20% (i.e., the coefficient of variation COV = 20%) and the sample mean from a pilot study has been found to be 1,000. Assuming a 95% confidence level and acceptable margin of precision in measurement is 200 (Rα = 200), determine the minimum number of roughness measurements to be recorded at each test segment
