You use a t-scoreâalso known as a Student's t-distributionâwhen you want to estimate a population statistic, such as the mean, or compare two groups of data. The t-score gives good results from small samples as long as the sample data form a bell-shaped curve when graphed.
The only fortified wine that can stand open any length of time is Madeira. That'll be good for 6 months. All the rest (port or sherry or marsala), depending on what it is exactly, only maximum, 2 weeks. After that, absolutely no good. And even 2 weeks is pushing it for some fortified wines. cheers, Bonnie.
Marsala Wine Information. Marsala is the west section of Sicily, the island near the foot end of Italy. In 1798 the Sicilians managed to substitute their own wines in place of the standard rum in an English naval shipment. In those seafaring days, something had to be done to wine to allow it to last the long ocean journeys.
