An article considered various issues associated with determining endotoxin concentration. The following data on concentration (EU/mg) in settled dust for one sample of urban homes and another of farm homes was kindly supplied by the authors of the article. U: F: 6.0 5.0 11.0 33.0 4.0 5.0 80.0 18.0 35.0 17.0 23.0 4.0 14.0 11.0 9.0 9.0 8.0 4.0 20.0 5.0 8.9 21.0 9.2 3.0 2.0 0.3 (a) Determine the value of the sample standard deviation for each sample. (Hint: [ x, = 237.0 for the urban sample and 128.4 for the farm sample, and I *2 = 10,079 for the urban sample and 1617.94 for the farm sample.] (Round your answers to two decimal places.) urban-settling farm-settling S = S = Interpret these values. the average endotoxin concentration in urban homes, and the endotoxin concentration in a farm home typically deviates from the mean by an The endotoxin concentration in an urban home typically deviates from the mean by an amount that is ---Select--- amount that is --Select- the average endotoxin concentration in farm homes. Contrast variability in the two samples. The variability in endotoxin concentration is far less in urban homes than in farm homes. The variability in endotoxin concentration is far greater in urban homes than in farm homes. The variability in endotoxin concentration is similar in urban homes than in farm homes.
