  1. QUOTE (kev211 @ Nov 19, 2009 -> 08:50 PM) Literally I just learned how to do this like the last few days in my stats class. I don't know what they mean H(sub 0) but I'm assuming its H(sub o) and H(sub a) Ho: X1=X2 Ha: X1=/=X2 Sample 1: (Male) N1= 43 X1= 21 S1=5 Sample 2: (Female) N1= 56 X1=20.8 S2=1.8 Alpha = .01 Using P-Value Finding the test Statistic Z = (X1-X2)/SQRT(S1^2/N1+S2^2/N2) Z=(21-20.8)/SQRT(5^2/43+1.8^2/56) Z=(.2)/SQRT(.58139+.05785) Z=(.2)/SQRT(.63925) z=0.25 P(Z>0.25) Looking at the table we fine the area to the right of Z = 0.25 to = .4013 Pvalue = .4013 Since its a two-tailed test double it Pvalue = .8026 Since Alpha .01(signifigance level) is less then the P-Value of .8026 you fail to reject the claim that there is a difference of scores between males and females. I just learned this so I may be wrong, but I'm pretty sure I'm right so maybe someone can check over my work. Very nice, but I see two issues. First, I think you got your final interpretation backwards. a non-significant calculated P-value will cause you to fail to reject the null (no difference), but you indicated you should "fail to reject the claim that there is a difference", so I think you just got it crossed in the end. I'm also questioning your interpretation of one- versus two-tailed tests. Certainly, yes, this is a two-tailed comparison since there is no a priori reason to assume one gender is smarter than the other. But, that means you will have to split your rejection area between the two tails of the bell curve. Logically that suggests you should halve the look-up (table) value rather than doubling it because you can't place your entire rejection area on just one side of the distribution. Am I misinterpreting something on that?
  2. QUOTE (Tex @ Nov 19, 2009 -> 11:17 PM) I am finally starting to put together a tiki bar. Sipin Safari is a great read. BTW jim, I picked up The Complete Joy of Homebrewing. Very interesting. I may have to order a second copy for the birthday gift, this one may show some signs of wear lol Charlie Papazian pretty much invented American homebrewing. You can get way more complicated and technical about the hobby than what he puts in his books, but everybody starts out with him if they are doing it right.
  3. QUOTE (Tex @ Nov 20, 2009 -> 06:54 AM) Quite the prognosticator procrastinator back then. Was that really three months ago Repaired that for ya.
  4. QUOTE (Pants Rowland @ Nov 19, 2009 -> 05:17 PM) Who are you, Gerald Ford? Sit, Liberty, Sit!
  5. QUOTE (ChiSox_Sonix @ Nov 19, 2009 -> 04:46 PM) You can't make up the H0 and H1 hypotheses without a conclusion. You need one or the other to answer this. You can find the P-value off of a chart if by using your N-values and the alpha value, which in this case is 'plus or minus' .001 But, there just isn't enough information here. I don't even see what the question is or what the claim is supposed to be...? There is enough information to perform an F-Test comparing standard deviations. Don't ask me how to do the math by hand, I gave that up as a bad habit long ago. Then again, that is only going to test the validity of a key underlying assumption of parametric statistics — that the two samples are drawn from the same statistical population. H0 is no difference between boys and girls and H1 is that there is a difference, right? With the means differing by 0.2, large sample size, very large standard deviations, and a 1% confidence level to reject the null, I can pretty much guarantee no statistical difference here. But I refuse to do the math because SoxTalk promised there would be no math.
  6. QUOTE (BigEdWalsh @ Nov 19, 2009 -> 04:37 PM) How the heck could you forget Zeppelin?! And be nice to albinos!! But you're right that would have been one ug...er...interesting-looking band. I realized it the day after I submitted my list and I've been kicking myself ever since.
  7. QUOTE (Felix @ Nov 19, 2009 -> 04:14 PM) Of course, I made the mistake of forgetting to put Cream on my list. You and me both, though for me it was less forgetting and more of them being just at the cusp of making it. Zeppelin on the other hand I just plain forgot.
  8. Brain Salad Surgery — fine ELP album with a spiffy Geiger cover to boot.
  9. QUOTE (BigEdWalsh @ Nov 19, 2009 -> 03:41 PM) "Factoid: Eric Clapton was actually shy about singing. Early on, he occasionally harmonized with Jack Bruce in Cream but, in time, took lead vocals on some notable Cream tunes including "Four Until Late", "Strange Brew", "Crossroads", and "Badge"." There's a video of early Cream doing "Strange Brew" and Clapton looked indeed very nervous and uncomfortable singing on camera. Factoid, Eric Clapton barely has a chin which is why he wears a beard, and Ginger Baker is a crazy ugly dude who should have joined a band with Edgar and Johnny Winter simply for the sake of being the world's ugliest band.
  10. QUOTE (Balta1701 @ Nov 19, 2009 -> 03:35 PM) We haven't banned dead languages from this thread? Xylene would likely then be a word unusable in this thread, as it derives from the Greek word for wood. This group of solvents are found in wood tar so the Greeks seem to have known a thing or two about a thing or two.
  11. Old Fart here who admits to liking Green Day. They didn't make my Top 20, but then again there were only around 20 or so acts that did. I think Dookie was their best outing, sure, but I admire the scope and ambition of the last two albums, and I think their music is a lot more intelligent than the majority of what is released today.
  12. Veritas Serum would keep all of y'all from lying to each other.
  13. QUOTE (southsider2k5 @ Nov 19, 2009 -> 09:06 AM) Yup, now my age and complete disconnection from music today is showing as I keep asking "who"? Sinatra. All the hip kids are listening to him.
  14. QUOTE (Felix @ Nov 19, 2009 -> 08:16 AM) Oh god... Green Day. I'm all sorts of sad right now that Soxtalk members apparently enjoy Green Day more than Talking Heads (and Pearl Jam and Soundgarden and Queens of the Stone Age and just about everyone else on this list) Just take it in stride. I have it on good authority, Frank is a LOCK for the top spot.
  15. Old Fezziwig has been the only reason I've bought the holiday samplers for years. And friggin' Sam Adams knows that and it's why they don't sell it on its own. Jim Koch is really a jerk a lot of the time. 20+ years ago, you could actually get single large bottles of fezziwig (I think pints, but maybe they were bombers, I don't remember). That's when I fell in love with the stuff. I made the mistake of trying a barrel-aged vanilla holiday thing from AB two years ago and it was absolutely putrid — maybe the least unbalanced beer I've ever tried. My mom thought is was wonderful (she's nuts), so at least a bottle or two was spared from the drain. And unlike G&T, I will pour a totally crappy beer down the drain. I try my best to choke down almost everything on principle, but sometimes it's a losing battle.
  16. Man of Steel or Mountain of Flab? You Make the Call!
  17. Kilocalories in the pint I'm about to polish off clock in at 960. Yikes.
  18. I love Cherry Garcia ice cream, and I don't care who knows it.
  19. QUOTE (knightni @ Nov 18, 2009 -> 10:41 PM) I tried to (example, not actuality) balance two guys putting Slipknot at #2 with 4 guys putting CCR as their #11 by adding bonus points for each list that the artist was on, but sometimes, the numbers are just unadjustable. Maybe someone's just not trying hard enough. . .
  20. QUOTE (southsider2k5 @ Nov 18, 2009 -> 10:32 PM) Funny thing is that money won't change me at all... I have always been a dick. GO NADS!!!
  21. The first incarnations of Sam Cranberry Lambic and Cherry Wheat were honestly among the worst beers I ever tasted. I'm not sure I can bring myself to try them again.
  22. QUOTE (knightni @ Nov 18, 2009 -> 07:35 PM) He and I were the only two to vote for them. Seems to me like the Guy in charge of the list can make things happen with the list, if you catch my drift.
