1. Given a coin you don’t know it’s fair or unfair. Throw it 6 times and
get 1 tail and 5 head. Determine whether it’s fair or not. What’s your
confidence value?
我的答案是：
H0: the coin is fair
Ha: the coin is unfair
X is the number of heads
Rejection region: |X - 3| > 2, i.e., X = 0,1,5,or 6

发帖数: 17096 | 11 虽然才第三个sequence，比前面强，不知道为啥第一开始的画面那么差
后面反而好了很多，细节也比较丰富
剧情一如既往，口音太重要看字幕
新加的小任务，guild那些跟yakuza有点神似啊
一开始买了很多商店，赚钱有什么用啊最后？还有很多装备都被锁了，比如想买把剑告

发帖数: 60932 | 20 For those who missed out on the QVC deal. I stumbled across this on
vitamixes website.
I believe this is the 5000 series Product Link:
https://secure.vitamix.com/acb/stores/4/Factory-Reconditioned-Vitamix-
Machine-SPECIAL-P2142C119.aspx
Its listed at 379.00 but when you add promo code 06-003511 takes 25.00 off
any 5200 model so this very well might be a 5200 oh yeah this has a 5 year
warranty

which to me means combining multiples of things to really score. This will
involve buying two Staples coupons from somewhere (I get them from the club
, google " staples", follow the first link, they are real coupons and his
customer service really is good), and three rebates - 2 Staples Easy Rebates
, and one Mail in Rebate. I'll break this down Potato head style for so
everyone can follow, in order:

发帖数: 60932 | 23 Drugstore.com has the Philips HeartStart Home (AED) Defibrillator M5068A for
$1267.99 (same price as Amazon.com).
With the current 15% off promotion from Steveb3163's post, that knocks the
price down to $1085.29.
In addition, there is a $50 off instant rebate link on the defib page that
now brings the cost down to $1035.29 shipped.
On top of that, you will earn $63.40 in drugstore.com dollars, now making
the price $971.89 after rebate, after Facebook, and after drugstore.com cash
back.

发帖数: 60932 | 24 heeeeeeeeeeyyyyyyyyy yyyyyy ya'll
Here's what I put together for this weekend's Staples sales. The reason I
made my own thread and deal is because everything I do can be done from a
distance, i.e., I don't even need to be in the country to do this deal. All
these things are available from Staples.com, with no need to go to a store.
So let's do this.
This will involve buying two Staples coupons from somewhere (I get them from
the Sder club, google "sder staples", follow the first link, they ar... 阅读全帖 |

dynamic contrast ratio, 60Hz, 2ms, HDMI, VGA, DVI, Built-in Speakers
Price is $229.99 on the site. But you can apply Discover Card Cashback
through ShopDiscover.com (5.0%) on this deal, making it effectively $218.49
before tax and shipping.
This is lower than ANY other place (Newegg, TigerDirect, Amazon, eBay, etc).

发帖数: 60932 | 26 Full credit to Russo69, who posted the deal in BF forum here but it is
getting ZERO attention (looks like searching the forums does not also search
the BF forums where this was posted originally). Same deal for $300
shipped sold out at Newegg pretty quick.
Amazon just matched the $300 price from Newegg, but the deal is better via
TigerDirect:
Tigerdirect.com has it for $280 plus shipping. Shipping was a reasonable $9
for me, so $289 shipped minus 5% Discover CB = $276 after cash back (ACB).
