Hi Everyone I need advice on how to verify a statistical experiment.
The question is to determine whether emission reductions from two different fuels are statistically significant. The test procedure was: the emissions of 12 similar engines were tested twice, first with a normal fuel (Fuel A) and second time with an improved formula (Fuel B). The results showed that on average the reductions in emissions when using fuel B was significantly lower, however I know enough statistics that this does not necessarily mean the results conclusively demonstrate that Fuel B is better than Fuel A. I would need to prove that the results is statistically valid Can anybody advice me in how to do this? . . ================================================================= Instructions for joining and leaving this list, remarks about the problem of INAPPROPRIATE MESSAGES, and archives are available at: . http://jse.stat.ncsu.edu/ . =================================================================
