A grоup оf 80 hоmeowners wаnts to investigаte whether the type of pаint and room lighting affect the perceived brightness of a room. Half of the participants were put in a room with matte finish paint, and the other half were put in a room with gloss finish paint. Within each paint finish group, 10 participants evaluated the room under LED lighting, 10 under incandescent lighting, 10 under fluorescent lighting, and 10 under natural daylight. The design of this experiment is a 2x4 factorial design with Paint Finish having two levels and Lighting Type having four levels. At the end of the evaluation, participants measured and reported the perceived brightness of the room in lumens. The data is shown below.

Use a level of significance (alpha) of 0.05. What is the F-statistic for the Paint Finish main effect? Round to one decimal place [a] What is the F-statistic for the Lighting Type effect? Round to one decimal place [b] What is the F-statistic for the interaction between Paint Finish and Lighting Type? Round to one decimal place [c]
