Question-Does the type of painting and the tray on which the parts are placed affect the mean hardness of the enamel paint? Produce a set of graphs to show your conclusion. Do also include explanatory text under each graph to describe patterns and behaviors in experimental or observational data that you found.
Hello. help. do not copy from others. show formulas used .
A study is carried out to analyze whether the type of painting, among three types available, affects the hardness of a certain type of enamel. The firing of the parts is done in an oven with four trays, one above another, and with 15 parts on each. Since it can be assumed that the tray might have an influence on the result, because of its position in the oven, a blocked design is used putting five parts of each type of painting on each tray.
The following hardness measures are obtained: Photo
