You are curious whether acts of kindness have the same effect on college students. You convince your psychology professors to assign their students to do three random acts of kindness a week for a semester. At the end of the semester, you test the happiness of the students. You find that they have a mean happiness level of 6.55 (out of 8) with a standard deviation of 0.60. The national mean level of happiness for college students is 5.90 with an unknown standard deviation. Given this, would you start doing three random acts of kindness a week?
