A manufacturer of sport shoes must control the water resistance of the product. Water resistance is measured by the amount of water (height in millimeters) that can be suspended above the fabric before water seeps through. The mean and standard deviation of the normally distributed variable have been estimated at u = 3114 mm and o = 135 mm. According to some newly introduced specifications, the desired water resistance should be between 2900 and 3700 mm. What is the upper limit of the natural tolerances range for the water resistance variable? Your answer:
