A chemist wants to compare two distinct corrosion inhibitors, A and B. In the experiment, 30 panels were immersed in a solution containing sulphuric acid and inhibitor A for four hours, whereas the other 30 panels were immersed in a solution containing sulphuric acid and inhibitor B for four hours. To assign the panels to one of the two inhibitors, randomly permuted blocks of varied lengths (2, 4 and 6) were utilized. Weight reduction over a four- hour period is the key response variable. Your job is to see if there is enough evidence to say whether there is a difference in normal weight loss between the two types of inhibitors in general. Question: Make appropriate graphical and numerical summaries. Use these summaries to express your subjective opinions on what you believe the facts are saying about the topic of interest.
