Biological Statistics I Biometry 301 / Natural Resources 313 Lab 6 Name: Jackie Lewis Section: 1 Date: 10-8-07 The vulnerability of inshore environments to contamination due to urban and industrial expansion in Mombasa is discussed in the paper “Metals, petroleum hydrocarbons and organochlorines in inshore sediments and waters on Mombasa, Kenya” ( Marine Pollution Bulletin , 1997, pp. 570-577). A geochemical and oceanographic survey of the inshore waters of Mombasa, Kenya was undertaken during the period from September 1995 to January 1996. In the survey, suspended particulate matter and sediment were collected from 48 stations within Mombasa’s estuarine creeks. The concentrations of major oxides and 13 trace elements were determined for a varying number of cores at each of the stations. In particular, the lead concentrations in suspended particulate matter (mg kg -1 dry weight) were determined at 37 stations. The researchers were interested in determining whether the average lead concentration was greater than 30 mg kg -1 dry weight. The data are given in the following Splus/R command for your use. Kenya.lead = c( 48, 53, 44, 55, 52, 39, 62, 38, 23, 27, 41, 37, 41, 46, 32, 17, 32, 41, 23, 12,  3, 13, 10, 11,  5, 30, 11,  9,  7, 11, 77,210, 38,112, 52, 10,  6)
