We would like to investigate if positive and negative affect measure really different concepts

(beyond the direction of these variables being opposite) in the United Nations’ World Happiness Report. To do so, we first reverse the negative affect score of each nation, by calculating NegAffectRev = 1 - NegAffect. As a first part of our investigation, we will perform a hypothesis test of equal population means. Ensure you choose the proper design for that test. Using the 2020 values for PosAffect and NegAffectRev in the data file Happiness Report Data, perform an analysis and prepare a short report on the difference in means of these two variables. Assume normality and data to be a representative samples.
