A machine shop uses two lathes to make shafts for electric motors. A sample of five shafts from each lathe are checked for quality-control purposes. The diameter of each shaft (in inches) is given as follows: Lathe I Lathe II 0.501 0.503 0.498 0.504 0.502 0.495 0.497 0.497 0.502 0.501 The mean diameter in each sample is 0.500. Find the standard deviation for the sample of shafts checked from Lathe 01 and Lathe 02. Which lathe is more consistent and why

Atextile fiber manufacturer is investigating a new drapery yarn, which the company claims has a mean thread elongation of 12 kilograms with a standard deviation of 0.5 kilograms. the company wishes to test the hypothesis upper h subscript 0 baseline colon mu equals 12 against upper h subscript 1 baseline colon mu less-than 12 using a random sample of n equals 4 specimens. calculate the p-value if the observed statistic is x overbar equals 11.8. round your final answer to five decimal places (e.g. 98.76543).
