The production of a polymer fiber follows a normal distributionwith a true mean diameter of 65 µm and a standard deviation of 22µm. Compute the probability of obtaining a fiber from 44 µm to 77µm. Of 10,000 fibers produced on Tuesday, the quality assuranceteam determines that 838 are too large and 537 are too small.Estimate the size range that the quality assurance team would allowas an acceptable fiber diameter.
