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.
Bottles will keep for 7-10 years. Pinot Noir: Consume within 5 years. Merlot: Keep no more than 3-5 years. Zinfandel: This red wine will last for 2-5 years. Ageing is typically a red wineâs game; most whites donât have the tannins to keep for more than 18 months or so. Among the more age-worthy whites: Chardonnay: 2-3 years.
