Question

the diameters of bolts produced in a machine shop are normally distributed with a mean of 6.26 millimeters and a standard deviation of 0.07 millimeters. find the two diameters that separate the top 3% and the bottom 3% the diameters of bolts produced in a machine shop are normally distributed with a mean of 6.26 millimeters and a standard deviation of 0.07 millimeters. find the two diameters that separate the top 3% and the bottom 3% the diameters of bolts produced in a machine shop are normally distributed with a mean of 6.26 millimeters and a standard deviation of 0.07 millimeters. find the two diameters that separate the top 3% and the bottom 3%

Explanation / Answer

The diameter that separates top 3% would be 22.26+3*qnorm(0.97) = 27.90238 and the one that separates the bottom 3% would be 22.26-3*qnorm(0.97) = 16.61762
