Motorola used the normal distribution to determine the probability of defects and the number of defects expected in a production process. assume
a production process produces items with a mean weight of 14 ounces.
a. the process standard deviation is 0.10 ounces, and the process control is set at plus or minus 1.75 standard deviations. units with weights less
than 13.825 or greater than 14.175 ounces will be classified as defects. what is the probability of a defect (to 4 decimals)?
in a production run of 1000 parts, how many defects would be found (round to the nearest whole number)?
