 Problem #1 |
Based on the left armature data from Homework Set Number 1, determine if the process is normally distributed using normal probability paper and graphically determine the percent out of specification limits (0.330 +/- .005) Graphically determine the Average, and 6 sigma spread of the data. |
| Problem #2 |
Based on the following test data determine, by use of normal prbability paper if the spot weld test strength is capable of meeting the minimium test specification of 130 newtons. Graphically determine the Average, and % out of specification. Strengths (N): 142, 146, 150, 154, 158, 162, 166 |
