Suppose your manager indicates that for a normally distributed data set you are analyzing, your company wants data points between z=−0.6z=-0.6 and z=0.6z=0.6 standard deviations of the mean (or within 0.6 standard deviations of the mean). What percent of the data points will fall in that range?Answer: percent (Enter a number between 0 and 100, not 0 and 1 and round to 2 decimal places)
Total plasma volume is important in determining the required plasma component in blood replacement therapy for a person undergoing surgery. Plasma volume is influenced by the overall health and physical activity of an individual. Suppose that a random sample of 50 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). Assume that ? = 7.20 ml/kg for the distribution of blood plasma.
Suppose that a machine has been calibrated so that the amount the material dispensed deviates from its specified target is normally distributed with a mean of 0 grams and a standard deviation of 1 gram. A single amount of material is dispensed. Let Z represent the amount the material dispensed deviates from it specified target. What amount of deviation represent the highest 3.59%? That is, if P(z > c) = 0.0359, find c. Round your answer to 2 decimals. c = grams. Add Work

There are many situations in which we want to compare means from populations having standard deviations that are equal. This method applies even if the standard deviations are known to be only approximately equal. Consider a report regarding average incidence of fox rabies in two regions. For region I, n1 = 16, x1 ≈ 4.73, and s1 = 2.84 and for region II, n2 = 15, x2 ≈ 3.93, and s2 = 2.45. The two sample standard deviations are sufficiently close that we can assume ?1 = ?2. Use the method of pooled standard deviation to consider the report, testing if there is a difference in population mean average incidence of rabies at the 5% level of significance. (Round your answer to three decimal places.) t =

Our environment is very sensitive to the amount of ozone in the upper atmosphere. The level of ozone normally found is 4.6 parts/million (ppm). A researcher believes that the current ozone level is at an excess level. The mean of 14 samples is 4.9 ppm with a variance of 1.2 Does the data support the claim at the 0.01 level? Assume the population distribution is approximately normal. Step 2 of 5 : Find the value of the test statistic. Round your answer to three decimal places.
