Exposure to microbial products, especially endotoxin may have an act on Vulnerability to alergies. The following are data on concentration (tu/mo) setted out for one ample of urban homes and another of farm nomes U 60 50 11.0 330 40 50 50.0 18.0 350 120 230 F: 60:13.0 12.0 0 0.0 7.040 17.0 3.0 220 240 2002 USE SALT (a) Determine the sample mean for each samochound your answers to four decimal places) urbanhomes Em farm homes cum How do they compare? The average endet in concentration in urbanhomes is more than double the average concentration in farm homes The average endotoxin concentration in farm homes more than double the average concentration urban homes, The werage and concentration is about the same in both urban and form home
(b) Determine the sample median for each sample urban homes EU/mg farm homes EU/mg How do they compare? The median endotoxin concentration is about the same in both urban and farm homes. The median endotoxin concentration in urban homes is roughly double the median concentration in farm homes, The median endotoxin concentration in farm homes is roughly double the median concentration in urban homes. Why is the median for the urban sample so different from the mean for that sample? The mean and median for urban homes are so different because the measure different aspects of the distribution The mean and median for urban homes are so different because there are fewer observations. The mean and median for urban homes are so different because the few large values raise the mean but not the median (c) Calculate the trimmed mean for each sample by deleting the smallest and largest observation (Round your answers to four decimal places.) urban homes EU/mo farm homes EU/mg What are the corresponding trimming percentages? (Round your answers to two decimal places.) urban homes farm homes How do the values of these trimmed means compare to the corresponding means and medians? % 96 Urban homes: The trimmed mean is ---Select- the mean of the entire sample. The trimmed mean is Select the median of the entire sample. Farm homes The trimmed mean is Select the mean of the entire sample. The trimmed mean is ---Select- the median of the entire sample.
