The defect length of a corrosion defect in a pressurized steel pipe is normally distributed with mean value 27 mm and standard deviation 7.9 mm. LAUSE SALT (a) What is the probability that defect length is at most 20 me? Less than 20 me? (Round your answers to four decimal places) at most 20 less than 20mm (b) What is the 75 percent of the defect length disabution-that is, the value that separates the smallest 75% of al lengths from the largest 25%? (Round your answer to four decimal places) (e) what is the 15th percentile of the defect length distributon? (Round your answer to four decimal places) (d) what values separate the middle 80% of the defect length distribution from the smallest 10% and the largest 10% (Round your answers to four decimal places) smallest 10% largest 10%
