Question

I am having trouble solving this problem.  Can you please provide me with some help?  Thank you.  I appreciate it.

Kentrex, a maker of game consoles, wants to determine whether a proposed new advertising campaign will change gamers' perception of the brand.  To conduct the test, Kentrex selected a selected a panel of 6 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 of the null hypothesis that there is no difference in average before-and-after scores for the populations.  Use a significance level of 5%.

player 1 2 3 4 5 6
before 47 52 67 31 62 59
after 57 54 72 37 60 68
