ISE 4120: Quality and Reliability Engineering Homework 3 (Due on Thursday 2/27/2020 at the beginning of the class) Instruction - This assignment should be submitted online in Carmen. Sub- mit your report as one .pdf file and your Python codes for all problems as one .py file separately. Do not compress them into one file. The python code should be separated into different cells (using "#%%" command) for different problems and have a label for each problem. In your report include your python code for each problem along with the output in the order of the problems (no appendix), and a brief description of the results. Failure to follow this instruction will result in a penalty. For Python codes, you may refer to the 'stat infer.py' on Github. Problem 6. (15 pts) The diameter of a metal rod is measured by 12 inspec- tors, each using both a micrometer caliper and a vernier caliper. The results are shown in Table 1. Is there a difference between the mean measurements produced by the two types of caliper? Use a = 0.01. (Assume that the Inspector Micrometer Caliper Vernier Caliper 0.150 0.151 0.151 0.150 0.151 0.151 0.152 0.150 0.151 0.151 0.150 0.151 0.151 0.153 0.155 0.152 0.154 0.151 0.151 0.151 0.150 0.151 0.152 0.153 Table 1: Measurements Made by the Inspectors for Problem 6 variances of two populations are equal.)
