- Trace metals in drinking water affect the flavor and an unusually high concentration can pose a health hazard. Ten pairs of data were taken measuring zinc concentration in bottom water and surface water. The raw data provided in table below. Does the data suggest that the true average concentration in the bottom water exceeds that of surface water? Use ?=0.01.A population of score has μ = 44. in this population, a score of X = 40 corresponds to z = -0.50. What is the population standard deviation?Total plasma volume by the overall health and physical activity of an individual. Suppose that a random sample of 40 male firefighters are tested and that they have a plasma volume sample mean of x = 37.5 ml/kg (milliliters plasma per kilogram body weight).

- A liquid-dispensing machine has been designed to fill bottles with 1.0 liter of liquid. The standard deviation of the process is 0.2 liter. A control chart is shown. The chart has horizontal lines drawn at the mean, μ, at μ ±20, and at μ±30. Determine if the process shown is in control or out of control. Explain. Liquid Dispenser Liquid dispensed (inters) 0- Click to select your answer. 4 5 6 7 8 9 10 Observation number G Is the process in control or out of control? Choose the correct answer below. OA. In control, because none of the three warning signals detected a change. OB. Out of control, because a point lies more than three standard deviations from the mean. OC. Out of control, because two out of three consecutive points lie more than two standard deviations from the mean. OD. Out of control, because there are nine consecutive points either above or below the mean.Overproduction of uric acid in the body can be an indication of cell breakdown.
