• B)People who wanted to quit smoking to improve their appearance (M = 66.91) were significantly more successful at quitting than those who wanted to quit to improve their health (M = 54.09), U = −2.04, z = 188.57, p = .04.
• C)People who wanted to quit smoking to improve their appearance were significantly more successful at quitting than those who wanted to quit to improve their health, U = 1415.50, z = −2.04, p = .04.
