5. Sulfur compounds may cause wine to smell slightly off so wine-makers want to know the odor threshold, the lowest concentration of a compound that a human nose can detect." The odor threshold for dimethyl sulfate for trained wine tasters is 25 micrograms per liter. The odor threshold for untrained tasters has a standard deviation of o - 7 micrograms per liter. A sample of 10 untrained students found the following thresholds: 30 42 30 35 22 33 31 29 19 23. Is this evidence that the average threshold for an untrained wine taster is above 25 micrograms per liter? Perform a hypothesis test
