Several factors can impact the structural soundness of 3D-printed objects, including the “struts” that connect various pieces. The following data appears in the article “Analyzing the Effects of Temperature, Nozzle- Bed Distance, and Their Interactions on the Width of Fused Deposition Modeled Struts Using Statistical Techniques Toward Precision Scaffold Fabrication”(J. Manuf. Sci. Engr. 2017). Response values are strut widths, in microns.

Perform a complete two-factor ANOVA, and report your findings.
