Perfluorooctanoic acid (PFOA) is a chemical used in products that coat cookware to prevent food from sticking. An agency is investigating the potential risk of PFOA as acancer-causing agent. It is known that the blood concentration of PFOA in the general population has a mean of u = 6 parts per billion (ppb) and a standard deviation ofG= 10 ppb. An article reported on tests for PFOA exposure conducted on a sample of 325 people who live near a factory that makes one such nonstick cookware product.Complete parts (a) and (b) below.Click the icon to view the table of normal curve areas.a. What is the probability that the average blood concentration of PFOA in the sample is greater than 7.5 ppb?P(x>7.5) =O (Round to three decimal places as needed.)b. The actual study resulted in x= 300 ppb. Use this information to make an inference about the true mean (u) PFOA concentration for the population that lives near thefactory.O A. µ<6O B.

The size of the left upper chamber of the heart is one measure of cardiovascular health. When the upper left chamber is enlarged, the risk of heart problems is increased. A paper described a study in which the left atrial size was measured for a large number of children ages 5 to 15 years. Based on this data, the authors concluded that for healthy children, left atrial diameter was approximately normally distributed with a mean of 26.2 mm and a standard deviation of 4.8 mm. (You may need to use a table or technology. Round your answers to four decimal places.) Approximately what proportion of healthy children have left atrial diameters less than 24 mm? Approximately what proportion of healthy children have left atrial diameters greater than 32 mm? Approximately what proportion of healthy children have left atrial diameters between 25 and 30 mm? For healthy children, what is the value (in mm) for which only about 20% have a larger left atrial diameter? mm

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.

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.)
