4. Triclоsаn is а cоmpоund often аdded to products such as soaps, lotions, and toothpaste. It is antimicrobial, so we expect it to lower one's chance of having a staph infection. However, the opposite was found in a recent study.1 Microbiologists swabbed the noses of 90 people, and recorded which had detectable levels of triclosan and which had evidence of carrying the staph bacteria, which greatly increases one's chance of having a serious staph infection. The results are shown in the table below. Use the results of this study to estimate the difference in the proportion of people with staph bacteria, between those with triclosan in their system and those without (proportion for those who have triclosan in their system – proportion for those who do not have triclosan in their system). (As a result of this study and others, the US Food and Drug Administration is investigating whether adding triclosan to personal care products is safe and effective.)  1Mole B, "Triclosan aids nasal invasions by staph," Science News, April 15, 2014.     Click here to access StatKey.
