Kentrex, a maker of game consoles, wants to determine whether a proposed new advertising campaign will change game players’ perception of its brand. To conduct the test, Kentrex selected a panel of six game players and used an extensive questionnaire to measure brand perception before and after the panel is shown the new campaign through a series of ads. Using the before and after brand perception scores in the table below, and assuming that the appropriate population conditions are satisfied, construct a hypothesis test to test the null hypothesis that there would be no difference in average before and after scores for the populations represented. Use a significance level of 5%.
