Public Policy and Political Science Regulations for a new office building specify that the median strength for nonmetallic, nonshrink grout should be 6000 psi when it is supporting concrete. A random sample of grout from various locations in an office building project was obtained, and the strength of each batch (in psi) was determined using the groutcube test at 28 days. Assume the underlying distribution of grout strength is continuous and symmetric. Use the Wilcoxon signed-rank test with a = 0.01 to determine whether there is any evidence that the median grout strength is different from 6000 psi. Find the p value for this test.
