Sulfur compounds cause "off-odors" in wine, and winemakers want to know the odor threshold – the lowest concentration of acompound that the human nose can detect. The odor threshold for dimethyl sulfide (DMS) in trained wine tasters is about 25micrograms per liter of wine (µg/L). The untrained noses of consumers may be less sensitive, however. A set of DMS odorthreshold data for 10 untrained students was analyzed.How sensitive are the untrained noses of students? You want to estimate the mean DMS odor threshold among all students, andyou would be satisfied to estimate the mean to within ±0.25 with 95% confidence. The standard deviation of the odor thresholdfor untrained noses is known to be o = 8 micrograms per liter of wine. How large an SRS of untrained students do you need?Give your answer rounded up to the nearest whole number.n =Incorrect

Answered: d for dimethyl sulfide (DMS) in trained…

Let x represent the hemoglobin count (HC) in grams per 100 milliliters of whole blood. The distribution for HC is approximately normal with μ = 14 for healthy adult women. Suppose that a female patient has taken 12 laboratory blood samples in the last year. The HC data sent to her doctor is listed below. We would like to know if the data indicates this patient has significantly high HC compared to the population. 20,17,15,15,22,21,16,16,20,22,15,21 Give the test statistic for this hypothesis test.

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.
A Show Time Remaining A The body lengths of deer mice are known to vary approximately normally, with mean 86 mm and standard deviation 8 mm. A research group is interested whether vitamin supplements will increase deer mouse body length. They select a random sample of 100 deer mice from the population of all deer mice that would ever receive vitamin supplements and observe their body lengths. Suppose the sample mean is calculated as 87.2 mm. Let u be the mean body length of deer mice who receive vitamin supplements. Provide the null and alternative hypotheses most appropriate for this situation. O A. Ho: H = 86 vs. Ha: P> 86 B. Họ: H = 87.2 vs. Hạ: µ 87.2 Reset Selection
