A 2012 study of freely forming groups in bars all over Europe examined the natural behavior of groups. The researchers recorded the group size (number of individuals in the group) of all 501 groups in the study that were naturally laughing. The findings were displayed in the figure below. 300 Number of groups 250 200 O 52 O 2.7 0 2 150 3.5 4 100 50 0 254 2 Enter your answer here The median laughter group size in this study is 168 3 The mean laughter group size in this study is O 100.2 Enter your answer here 52 4 5 Laughter group size 21 6 6 Can we conclude from these findings that, in European bars in 2012, smaller groups were more likely than larger groups to be naturally laughing? Explain your statistical reasoning in one sentence.
