The average tensile strength of carbon fiber cloth is 600 MPa. You are testing a new weaving pattern for the carbon fiber threads and want to know if this new weave causes a difference in the tensile strength. After testing 18 samples of the new weave, you found a sample average of 585 MPa with a standard deviation of 34 MPa. At a significance level of 0.05, test to see if this new weave has a different mean than 600...
