Chapter 7, Problem 52SE
High concentration of the toxic element arsenic is all too common in groundwater. The article “Evaluation of Treatment Systems for the Removal of Arsenic from Groundwater” (Practice Periodical of Hazardous, Toxic, and Radioactive Waste Mgmt., 2005: 152–157) reported that for a sample of n = 5 water specimens selected for treatment by coagulation, the sample
- a. Calculate and interpret a 95% CI for true average arsenic concentration in all such water specimens.
- b. Calculate a 90% upper confidence bound for the standard deviation of the arsenic concentration distribution.
- c. Predict the arsenic concentration for a single water specimen in a way that conveys information about precision and reliability.

A study by Bechtel et al., 2009, described in the Archives of Environmental & Occupational Health considered polycyclic aromatic
hydrocarbons and immune system function in beef cattle. Some cattle were near major oil- and gas-producing areas of western Canada. The
mean monthly exposure to PM1.0 (particulate matter that is <1μm in diameter) was approximately 7.2 µg/m³ with standard deviation 1.5.
Assume that the monthly exposure is normally distributed. What is the probability of a monthly exposure greater than 9 µg/m³ ? Round
your answer to three decimal places (e.g., 98.765).

- The paper "Trends in Blood Lead Levels and Blood Lead Testing among U.S. Children Aged 1 to 5 Years"t gave data on blood lead levels (in mg/dL) for samples of children living in homes that had been classified either at low, medium, or high risk of lead exposure, based on when the home was constructed. After using a multiple comparison procedure, the authors reported the following. 1. The difference in mean blood lead level between low-risk housing and medium-risk housing was significant. 2. The difference in mean blood lead level between low-risk housing and high-risk housing was significant. 3. The difference in mean blood lead level between medium-risk housing and high-risk housing was significant. Which of the following sets of T-K intervals (Set 1, 2, or 3) is consistent with the authors' conclusions?
