6.28 Modified You are to determine if exposure by oral ingestion to the chemicals xylene, toluene, arsenic, and hexavalent chromium poses a noncarcinogenic health risk. The chemical-specific reference doses (mg/kg-day) obtained from IRIS are: xylene (0.2), toluene (0.8), arsenic (0.0003), and hexavalent chromium (0.003) Assume a 70 kg individual consumes 2 liters of water per day with these chemicals dissolved at a concentration of 1 mg/L. Determine the HQ for the water.

An experiment was performed to determine the effect of four different chemicals on the strength of a fabric. These chemicals are used as part of the permanent press finishing process. Five fabric samples were selected, and a randomized complete block design was run by testing each chemical type once in random order on each fabric sample. The data are shown in Table below. test for differences in means using an ANOVA with α=0.01 Fabric Sample Chemical Type 1 2 3...

A study aimed to determine if grapefruit juice has beneficial effects on the pharmacokinetics of oral digoxin, a drug often prescribed for heart ailments. Seven healthy non-smoking volunteers participated in the study. Subjects took digoxin with water for 2 weeks, no digoxin for 2 weeks, and then digoxin with grapefruit juice for 2 weeks. The peak plasma digoxin concentrations (Cmax; ng/mL) when subjects took digoxin under the two conditions are given in the following table: Subject 1 2 3 4...

How would you rank the relative importance of transaction exposure, economic exposure, and translation exposure? Explain your answer. If you are the decision maker, will you hedge translation exposure? There are two approaches of hedging: 1) hedge only when we expect an unfavorable movement in foreign exchange rate, and 2) hedge anyway regardless of our expectation of exchange rate movements. Which approach would you use and why?

An investigation is conducted to determine if the exposure of women to atomic fallout influences the rate of birth defects. A sample of 500 children born to mothers who were exposed to the atomic explosion in Hiroshima was studied. A sample of 400 children from a Japanese island far removed from the site of the atomic explosion formed the control group. Suppose that the following data and R output for the incidence of birth defects were obtained. Expected counts are...
