Question:

The surface finish of 10 metal parts produced in a grinding process is as follows: (in micro inches): 10.32, 9.68, 9.92, 10.10, 10.20, 9.87, 10.14, 9.74, 9.80, 10.26. Do the data support the claim that the median value of surface finish is 10 micro inches? Use the sign test with a = 0.05. What is the P-value for this test?
