Two formulations of a certain coating, designed to inhibitcorrosion, are being tested. For each of eight peoples, half thepipe is coated with formulation A and the other half is coated withformulation B. Each pipe is exposed to a salt environment for 500hours. Afterward, the corrosion loss is measured for eachformulation on each pipe and the results are shown below. Can youconclude that the mean amount of corrosion differs between the twoformulation? Setup the test and show your p-value.
