### Understanding Wine Odors#### 17.40 This Wine StinksSulfur compounds are known to cause "off-odors" in wine. Winemakers aim to identify the odor threshold, which is the lowest concentration of a compound that can be detected by the human nose. Specifically, the odor threshold for dimethyl sulfide (DMS) in trained wine tasters is approximately 25 micrograms per liter of wine (µg/L). This level is crucial for winemakers to prevent unpleasant smells in their products.The image includes a "4 step" icon, which is likely part of a series or process related to wine tasting or production. ## Chapter 17: Tests of Significance: The BasicsNoses of consumers may be less sensitive, however. Here are the DMS odor thresholds for 10 untrained students:30, 30, 42, 35, 22, 33, 31, 29, 19, 23Assume that the odor threshold for untrained noses is normally distributed with σ = 7 μg/L. Is there evidence that the mean threshold for untrained tasters is greater than 25 μg/L?

It has been estimated that the 1991 G-car obtains a mean of 35 miles per gallon on the highway, and the company that manufactures the car claims that it exceeds the estimate in highway driving. To support its assertion, the company randomly selects 49 1991 G-cars and records the mileage obtained for each car over a driving course similar to that used to obtain the estimate. The following data resulted: x = 36.5 miles per gallon, s = 7 miles per gallon. %3D a. Find the observed significance level for testing Ho: u= 35 vs. Ha: u> 35. %3D b. For what value of significance level a, you will reject the null hypothesis.
