StatTip 2.23.13

StatTip 2.23.13: The simplest null hypothesis is that the sample mean value is not statistically different from the population mean value.

I may as well talk about our wine-tasting hobby!

My wife and I enjoy trying new wines, reds mostly, and I had the thought to blog a bit about our impressions.  So here goes with our first of a quartet of new-to-us stuff.

Valle Dorado Carmenere, Curico Valley, Chile, 2008 ($9 at Bueno Cheapo Vino)

We didn't have a clue about carmenere, but it's potent!  It slams you with some smoke initially, then moves into a berry and grit combo that goes pretty well with a 12-pack of Taco Bell tacos.  We're not exactly highbrow with our pairings, but wine is meant to be enjoyed, not elevated.
