An experiment was conducted to assess the effect of current and voltage on the tensile strength (ksi)
Question:
An experiment was conducted to assess the effect of current and voltage on the tensile strength (ksi) of welds made using a tungsten inert gas (TIG) welding tool, which resulted in the following data.
Use two-factor ANOVA to determine whether current or voltage impacts the tensile strength of welds under these experimental conditions at the .10 significance level. (Data is from “To Investigate the [E]ffect of Process Parameters on Mechanical Properties of TIG Welded 6351 Aluminum Alloy by ANOVA,” GE-Int. J. Engr. Res. 2014: 50–62.)
