American Greetings would like to test the hypothesis that the average amount of money spent per person on Mother's Day increased by more than $10 this year when compared to last year. The following data represents the amount of money that the same eight individuals spent on Mother's Day during the past two holidays. 



Define Population 1 as this year and Population 2 as last year and use the critical value approach to test this hypothesis with  α = 0.05.

  tα = 1.895

Because  = 1.03 is less than tα = 1.895, we fail to reject the null hypothesis. Therefore, American Greetings cannot conclude that the average amount of money spent per person on Mother's Day increased by more than $10 this year when compared to last year.
