Mercury is a persistent and dispersive environmental contaminant found in many ecosystems around the world. when released as an industrial by-product, it often finds its way into aquatic systems where it can have deleterious effects on various avian and aquatic species. the accompanying data on blood mercury concentration (µg/g) for adult females near contaminated rivers in a state was read from a graph in an article. 0.20 0.22 0.26 0.30 0.35 0.42 0.54 0.57 1.42 1.71 1.83 2.21 2.26 3.08 3.24 (a) determine the values of the sample mean and sample median. hint: xi = 18.61. (round your answers to three decimal places.) x = = explain why they are different. there is heavy negative skewness in the data. there is heavy positive skewness in the data. the sample mean and sample median are never equal. there are an odd number of data values. they aren't different since the data is symmetric. (b) determine the value of the 10% trimmed mean. (round your answer to three decimal places.) compare to the mean and median. it is the same as the mean. it is between the values of the mean and median. it is the same as the median. it is below both the mean and median. it is above both the mean and the median.

Aquality characteristic of new iphone x made at the amsterdam plant at apple computers has a manufacturing specification (in mm) of 0.200 +/- .07. historical data indicates that if the quality characteristic takes on values greater than 0.27 or smaller than 0.13 the component fails at a cost of20.19. based on these data: determine the taguchi loss function (must show work) calculate an estimated loss for a quality characteristic of .30 calculate an estimated loss for quality characteristic of .40.
