The DENR has a new procedure to detect algal bloom in water being tested. This new procedure
is important because, it could be used to detect three different contaminants-organic pollutants,
volatile solvents, and chlorinated compounds. The department claims that it can detect high
levels of organic pollutants with 99.95% accuracy, volatile solvents with 89.70% accuracy, and
chlorinated compounds with 99.70% accuracy. If an algal bloom is not present, the test does not
signal. Samples are prepared for the calibration of the test and 60% of them are contaminated
with organic pollutants, 27% with volatile solvents, and 13% with traces of chlorinated
compounds. A test sample is selected randomly.
Denote as follows: S = signal, O = organic pollutants, V = volatile solvents, C = chlorinated
compounds. If the test signals, what is the probability that chlorinated compounds are present?

Two random samples of 6 rats each were exposed to different environments. One sample of rats was held in a normal environment at 26°C. The other sample was held in a cold 5°C environment. Blood pressures and heart rates were measured for rats for both groups. The blood pressures for the 12 rats are shown in the table below. a. Provide a 95% confidence interval on the difference in the two population meansb. Do the data provide sufficient evidence that rats exposed to a 5°C environment have a higher mean blood pressure than rats exposed to a 26°C environment?

The soil was extracted with acid, and the extract was analyzed using flame atomic absorption spectrometry. In Area A, Pb concentrations were 1.2, 1.0, 0.9, 1.4 mg/kg. In Area B, Pb concentrations were 0.7, 1.0, 0.5, 0.6, 0.4 mg/kg. Are these two areas significantly different from each other with Pb concentrations at 90% confidence level?arrow_forward
- The purification of industrial waste is often a destructive process with manybeneficial components removed from the waste as part of the cleansing process. As part of some trials to reuse industrial sludge as a mulch for planting, conservation of existing nitrogen levels in the sludge is being studied. Nitrogen is used in plants to synthesize amino acids, proteins, chlorophyll, nucleic acids, and enzymes. Initial testing showed 1 kg of sludge contained 254 mg of nitrogen and after the cleaning process there were 189 mg of nitrogen left. What is the percentage reduction of nitrogen?arrow_forwardNatalie conducted a study on the effects of triclosan on three algae populations. She collected an algae sample from three different ponds, counted the number of algae cells present in the sample, and then exposed them to a 5 ppm aqueous solution of triclosan and re-counted the number of algae cells in each sample. Using a paired t-test, she obtained a p-value of 0.083 when comparing the original algae population sizes to the population sizes after exposure to triclosan. Natalie concluded that triclosan is toxic to algae because her data for the three samples showed a trend toward a reduction in population size. What could Natalie do to show a statistically significant effect of triclosan on algae population size?

- Can attack of a plant by one organism induce resistance to subsequent attack by a different organism? In a study of this question, individually potted cotton plants were randomly allocated to two groups. Each plant in one group received an infestation of spider mites; the other group were kept as controls. After 2 weeks the mites were removed, and all plants were inoculated with a fungus that causes wilt disease. According to the research question, H0: Miles do not induce resistance to wilt. Ha: Mites do induce resistance to wilt. What is the alternative hypothesis in symbols when p represents the proportion of wilt disease in a group? p1 < p2 or p1 > p2?arrow_forwardPolyunsaturated fatty acids in the diet favorably affect several risk factors for cardiovascular disease.

- Vermont maple sugar producers sponsored a testing program to determine the benefit of a potential new fertilizer regimen. A random sample of 27 maple trees in Vermont were chosen and treated with one of three levels of fertilizer suggested by the chemical producer. In this experimental setup, nine trees (three in each of three climatic zones) were treated with each fertilizer level and the amount of sap produced (in mL) by the trees in the subsequent season was measured. The results are presented in the following table. Southern Zone Central Zone Northern Zone 76.2 80.4 74.2 79.4 87.9 86.9 84.5 85.2 80.1 Low fertilizer Medium 87.0 95.1 93.0 98.2 94.7 96.2 88.4 90.4 922 fertilizer High 84.2 87.5 83.1 90.3 89.9 93.2 81.4 84.7 82.2 fertilizer Estimate the main effects of fertilizer levels and climatic zone, and their interactions. b.

Test the hypothesis that there is no interaction between fertilizer levels and climatic zone.…arrow_forwardA medical student at a community college in city Q wants to study the factors affecting the systolic blood pressure of a person (Y). Generally, the systolic blood pressure depends on the BMI of a person (B) and the age of the person A. She wants to test whether or not the BMI has a significant effect on the systolic blood pressure, keeping the age of the person constant. For her study, she collects a random sample of 150 patients from the city and estimates the following regression function: Y= 15.50 +0.90B + 1.10A. (0.48) (0.35) The test statistic of the study the student wants to conduct (Ho: B, =0 vs. H4: B, #0), keeping other variables constant is. (Round your answer to two decimal places.) At the 5% significance level, the student will v the null hypothesis. Keeping BMI constant, she now wants test whether the age of a person (A) has no significant effect or a positive effect on the person's systolic blood pressure.

PM is measured as “inhalable” particles 10 micrometers in diameter or “fine inhalable” particles 2.5 micrometers in diameter. Suppose that studies show, for a particular region, that cities exceed PM2.5 standards 20% of the time and exceed ozone standards 10% of the time. Assume that PM2.5 and ozone measurements are statistically independent. A) Determine the probability that a city, selected at random, exceeds one of the standards. B) If a city exceeds the standards, what is the probability that it exceeds only the PM2.5 standard?arrow_forward
