Question

DATA ABOVE (ONLY NEED B) b. Give a 96% confidence interval for the true mean threshold for those untrained tasters. 1.(use data:ex17-40WINE.jmp)Sulfur compounds cause "off odors"in wine,and winemakers want to know the odor threshold-the lowest concentration of a compound that the human nose can detect. The odor threshold for dimethyl sulfide (DMS) in trained wine tasters is about 25 micrograms per liter of wine.The untrained noses of consumers may be less sensitive,however. Assume that the oder threshold for untrained noses is Normally distributed with sigma=7. a. Is there evidence that the mean threshold for untrained tasters is greater than 25ug/L? Give HO, Ha, report test-statistic, p-value and your conclusion about this test. b.Give a 96% confidence interval for the true mean threshold for those untrained tasters 1 30 2 30 42 3 4 35 5 6 22 33 7 31 8 29 9 19 10 23
