The inspection was carried out using an inline digital micrometer. The specification for the tubing is 3.510.15mm. Assuming that the data set is normal complete the following: 1. IL III. Calculate the mean & standard deviation for the data set provided. Calculate the Cp & Cpk for the data set provide & graph your results on a number line. Based on your graph make a usage decision for the product manufactured during the shift. Make a suggestion on how to improve the performance of the process. IV.
