The pressures obtained from a manufacturing process of capillary tubes is found to be normally distributed with an average pressure of 130 pounds per square inch and a standard deviation of 4 pounds per square inch. Determine: a) What percent of the pressures are below 121 pounds per square inch? b) What percent of the pressure readings lie between 121 and 134 pounds per square inch?
