A researcher wanted to know which local brewery had the best IPA. Each participant tried a sample from all three different breweries (Ore Dock, Black Rocks, and Barrel + Beam) and was asked to rate each one on a scale of 0-100. Use the six steps of hypothesis testing to determine if there was a significant effect of brewery on IPA popularity ratings.
