Environmental Racism Refers To How Neighborhoods Populated Primarily By People Of Color And Low Socioeconomic Status Hou 1 (277.94 KiB) Viewed 29 times

Environmental racism refers to how neighborhoods populated primarily by people of color and low-socioeconomic status households are disproportionately exposed to environmental hazards. A recent NPR report highlighted how lead poisoning continues to affect children in the Midwest today, particularly Black children and children living in low-income neighborhoods. These neighborhoods are more likely to have older houses that contain lead-based paint or be located near a historic source of contamination such as a lead smelter. Researchers are continuing to investigate high levels of lead in children in lowa, Kansas, Missouri, and Nebraska. Suppose we have lead blood level data from a random sample of 80 children living in low-income neighborhoods in St. Louis, Missouri; the simulated data are in "lead.Rdata". We are interested in using this sample to construct a confidence interval for the population 75th percentile lead level. While formulas for such a confidence interval are not covered in this course, a simulation-based approach can be used to construct this interval. i. ii. Write a simulation that carries out the following steps for 10,000 iterations. Clearly comment your solution code. - Sample 80 values from lead with replacement. - Compute the 75th percentile of the sampled values. - Store the value of the 75th percentile. Determine the 2.5th and 97.5th percentiles of the 10,000 stored values. These values are the lower and upper bounds of an approximate 95% confidence interval for the population 75th percentile lead level.
