untrained noses

This wine stinks. Sulfur compounds cause “offodors” in wine, so 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 (μg/l). The untrained noses 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   23

Assume 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?
