Nonparametric: A small study is conducted to compare birth weight in babies born to mothers who do not smoke to those that smoke more than 2 pack/day. Is there a significant difference between birth weights due to maternal smoking status? Use the Mann-Whitney U test with a 5% level of significance. What is U1 (non-smokers)? Birth weights of infants in two groups of mothers. (Observed data) Heavy Smokers (21/2 pack/day) Nonsmokers 8.6 7.0 8.5 5.2 6.3 6.1 9.3 6.7 8.0 6.6 6.8 7.4 4.9 6.3
