Hi anyone who can help me with this? Would love to see workings and explanations, thank you.

(d) Other characteristics of the electrode are tested, and a more complex model is fitted to summarise the impact of the various characteristics and preparation techniques on porosity. The model fitted is summarised in table 4.2. What does the p-value associated with each term tell you, suggest a simplified model for porosity?
