Two formulations of a certain coating, designed to inhibit corrosion, are being tested. For each of eight pipes, half the pipe is coated with formulation A and the other half is coated with formulation B. Each pipe is exposed to a salt environment for 500 hours. Afterward, the corrosion loss (in µm) is measured for each formulation on each pipe. Pipe A B 197 204 2 161 182 3 144 140 4 162 178 185 183 154 163 136 156 8 130 143 Can you conclude that the mean amount of corrosion differs between the two formulations?
