2) Math Problem (8 points) Rind and Strohmetz (2001) found that waiters who wrote "thank you" or drew a smiley face on the check got bigger tips than those who wrote nothing. To replicate this finding, a researcher asked N = 12 waiters to either draw a smiley face, write "thank you," or write nothing on the check. Then, he measured how many dollars they were given as a tip. • Waiters who wrote "thank you" were given tips of (4, 2, 6, 4) dollars. • Waiters who drew a smiley face were given tips of (9, 3, 6, 6) dollars. • Waiters who did neither of these were given tips of (4, 0, 3, 1) dollars. Was there a significant overall relationship between writing on the check and the amount that waiters were tipped? (Use a = .05. Test the overall effect only; no post hoc tests.)
