Researchers, reporting in Chemical Senses (Roberts et al., 2005), were interested in whether body odor relates to genetics. Body odor was compared between adult identical twins who were not living together. Female identical twins were asked to follow a complex hygiene regimen and told not to come in contact with a variety of odors (garlic, smoke, perfume, etc.) for 24 hours prior to the collection of their odors. Pads were attached to the upper part of their bodies and covered up with a cotton t-shirt before the twins went to bed. The pads were collected the next morning. Sniffers were then assigned to sniff a pad and try to match the pad with one of four pads where one was from the identical twin and the other three were from non-relatives. The 113 sniffers correctly matched 42 odors to that of the twin. Do the data provide evidence the sniffers are more likely than random chance to make a correct match?What is the null hypothesis in words
