A study by Bechtel et al., 2009, described in the Archives of Environmental & Occupational Health considered polycyclic aromatichydrocarbons and immune system function in beef cattle. Some cattle were near major oil- and gas-producing areas of western Canada. Themean 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 ? Roundyour answer to three decimal places (e.g., 98.765).

Given: Meanμ=7.2standard deviation(σ)=1.5 X follows normal distribution. x=greater than 9

Total cholesterol in children aged 10 to 15 years of age is assumed to follow a normal distribution with a mean of 191 and a standard deviation of 22.4. what proportion of children 10 to 15 years of age would be classified as hyperlipidermic (assume that hyperlipidermia is defined as a total cholesterol level over 200?
Overproduction of uric acid in the body can be an indication of cell breakdown. This may be an advance indication of illness such as gout , leukemia or lymphoma. Over a period of months an adult male patient has taken even blood tests for uric acid. The mean concentration was x =5.30mh/dL. The distribution of uric acid in healthy adult males can be assumed to be normal, with standard deviation =1.95mg/dL. Find a 95% confidence interval for the population mean concentration of uric acid in this patients blood What is margin of error? Lower limit? Upper limit? And margin of error?

Mr. Matar Al Maqbali measured the concentration of Zinc ion in the wastewater received from Industrial samples on daily basis. He has drawn and consider a Gaussian distribution curve with a population mean of 10.254 mg/L and a population standard deviation of 0.155 mg/L. Find the fraction of measurements expected between 10.525 and 10.575 mg/L if many measurements are made.
Low‑density lipoprotein, or LDL, is the main source of cholesterol buildup and blockage in the arteries. This is why LDL is known as "bad cholesterol." LDL is measured in milligrams per deciliter of blood, or mg/dL. In a population of adults at risk for cardiovascular problems, the distribution of LDL levels is normal, with a mean of 123123 mg/dL and a standard deviation of 4141 mg/dL. If an individual's LDL is at least 11 standard deviation or more above the mean, he or she will be monitored carefully by a doctor. What percentage of individuals from this population will have LDL levels 11 or more standard deviations above the mean? Use the 6868–9595–99.799.7 rule. (Enter your exact answer as a whole number.)
Suppose that you wish to estimate the difference between mean pH measurements of rainfalls in two different locations, one in relatively unpolluted area and the other in an area subject to heavy air pollution. You want to be 95% confident that the margin of error for the difference between mean pH of rainfalls in relatively unpolluted area and mean pH of rainfalls in an area subject to heavy air pollution will not exceed 0.1 pH. How many rainfalls (pH measurements) must be included in each sample? Assume that the variance of pH measurements in a relatively unpolluted area is equal to 2 = 20, and the variance of pH measurements in an area subject to heavy pollution is equal to 2 = 0.25, and samples will be of equal size (n = n₂ = n). 2 It is supposed that values of pH in rainfalls are normally distributed in polluted and unpolluted areas. The number of rainfalls (pH measurements) that must be included in each sample is
Aldo, a highway safety inspector, is concerned about the potential for accidents caused by boulders that fall down a sandstone cliff beside a main highway. As part of an accident simulator, Aldo models the boulders' weights using a normal distribution with a mean of 556 kg and a standard deviation of 100 kg find the percentage of boulders that weigh less than 520kg or more than 592kg according to the model. .
Overproduction of uric acid in the body can be an Indication of cell breakdown. This may be an advance indication of liness such as gout, leukemia, or lymphoma. Over a period of months, an adult male patient has taken five blood tests for uric acid. The mean concentration was x- 5.35 mg/dl. The distribution of uric acid in healthy adult males can be assumed to be normal, with a-1.81 mg/dl. (a) Find a 95 % confidence interval for the population mean concentration of uric acid in this patient's blood. What is the margin of error? (b) What conditions are necessary for your calculations? (c) Interpret your results in the context of this problem. (d) Sample size Find the sample size necessary for 95% confidence level with a maximal margin of error E = 1.10 for the mean concentration of uric acid in this patient's blood. Thank you
The distribution of average wait times in drive-through restaurant lines in one town was approximately normal with mean �=185μ=185mu, equals, 185 seconds and standard deviation �=11σ=11sigma, equals, 11 seconds. A journalist wrote an article about the restaurants whose average drive-through wait times were in the top 25%25%25, percent for that town. What is the minimum average wait time for restaurants that the journalist included in the article?
According to a recent poll, 28% of adults in a certain area have high levels of cholesterol. They report that such elevated levels "could be financially devastating to the regions healthcare system" and are a major concern to health insurance providers. According to recent studies, cholesterol levels in healthy adults from the area average about 207 mg/dL, with a standard deviation of about 20 mg/dL, and are roughly Normally distributed. Assume that the standard deviation of the recent studies is accurate enough to be used as the population standard deviation. If the cholesterol levels of a sample of 44 healthy adults from the region is taken, answer parts a through d. a) What shape will the sampling distribution of the mean have? A. The sampling distribution of the mean is skewed right. B. The sampling distribution of the mean is normal. C. The sampling distribution of the mean is skewed left. D. There is not enough information to determine the shape of the sampling distribution. b)…
Peak expiratory flow (PEF) is a measure of a patient’s ability to expel air from the lungs. Patients with asthma or other respiratory conditions often have restricted PEF. The mean PEF for children free of asthma is 306. An investigator conducts a study to investigate whether there is a difference in mean PEF in children with chronic bronchitis as compared to those without asthma or other respiratory conditions that often have restricted PEF. Data on PEF are collected and summarized below. Based on the data, is there statistical evidence of a lower mean PEF in children with chronic bronchitis as compared to those without? Run the appropriate test at a = 0.05. Group Number of Children Mean PEF Std Dev PEF Chronic Bronchitis 25 274 59 No Chronic Bronchitis 25 317 73
