Susan loves her husband, but he has the annoying habit of yodeling after dinner on occasion. Yodeling is a type of singing that can be pleasant, however, her husband's attempts at yodeling are quite unpleasant. She is trying to figure out if he tends to yodel more when she serves wine with dinner. She has tracked data for 150 dinners and found the following. After 30 dinners her husband yodeled. She served wine 50 times. She served wine and he yodeled the same night 20 times. Does the wine affect his tendency to yodel? If so, does it make him more likely to yodel or less?
