Boxing Record

Clottey is 33 years old and stands 5ft 8in tall while Manny is two years younger than Clottey and stands at 5ft. 6.5in. It would be interesting to see the two fighters box it out on March 13, in the Dallas Cowboys stadium in Texas.

Pacquiao can deliver accurate and strong rapid-fire punches. Will Clottey suffers his first knockout loss?

Or will there be surprises? A win or a loss will not diminish the star of Pacquio.
And know this: Clottey never lost by knockout.

Here are the current betting(we don’t practice this since we have no money!) odds

Draw or Technical Draw 25/1
Joshua Clottey by Decision or Technical Decision 7/1
Manny Pacquiao by Decision or Technical Decision 1/1
Manny Pacquiao by KO or TKO or Disqualification 2/5
Joshua Clottey by KO or TKO or Disqualification 5/1

And a 700 dollar bet on Pacquiao will only earn you a hundred bucks and a refund of your 700 dollars.

I sometimes bought Pringles when I was still in Diliman because I liked to collect their tall cans. Of course I threw them away later. It is comforting that food manufacturers are alert to any contamination of their popular products. Here is a news clippings I cut from the Procter and Gamble home page only for the convenience of the reader. The home page is http://www.pg.com:

P&G Joins Industry Ingredient Recall by Voluntarily Recalling Two Flavors of Pringles(R) in the United States In Response to FDA Industry Guidance

CINCINNATI, March 8, 2010 /PRNewswire via COMTEX/ — The Procter & Gamble Company (NYSE: PG), in response to a recommendation from the Food & Drug Administration (FDA) to the food industry, announced today that it is voluntarily recalling Pringles Restaurant Cravers Cheeseburger potato crisps and Pringles Family Faves Taco Night potato crisps as part of an industry ingredient recall to protect consumers from potential Salmonella exposure. There have been no reports of Salmonella-related illness in relation to these products.

P&G was notified by one of its suppliers that a seasoning used in these two products contains hydrolyzed vegetable protein (HVP) manufactured by Basic Food Flavors, Inc., who has voluntarily recalled several lots of this ingredient because of potential salmonella exposure. As a result, the FDA has recommended that food manufacturers recall certain types of products containing HVP manufactured by Basic Food Flavors, and P&G is complying with this guidance.

Only products with the following “best by” dates are being recalled. The “best by” date for each product can be found on the bottom of the can.

No other Pringles varieties or flavors are affected by this recall. These two products represent only one half of one percent of Pringles’ U.S. volume. None of the affected products have been shipped to retailers outside of the United States.

The safety of our products is P&G’s top priority, and we follow rigorous food safety and ingredient testing standards. We are withdrawing these products out of an abundance of caution for consumer safety and in response to FDA’s recommendation to the food industry.

Salmonella is a common food borne pathogen that can cause severe illnesses, including fever, abdominal cramps and diarrhea. While most individuals recover without medical intervention, the infection can be life-threatening in some cases such as young children, the elderly and those with compromised immune systems. There have been no reports of Salmonella-related illness to date in relation to these products.

Consumers who have purchased the recalled products should discard the product and call P&G for a replacement coupon or refund at 1-877-876-7881 (Hours of operation: Monday – Friday, 9AM – 6PM US ET).

HVP or hydrolyzed vegetable protein , is a common “flavor-enhancer,” made by Basic Food Flavors, Inc., that has been found to be contaminated with salmonella.

A public school teacher was arrested today at John F. Kennedy International Airport as he attempted to board a flight while in possession of a ruler, a protractor, a compass, a slide-rule, and a calculator.

At a morning press conference, the Attorney General said he believes the man is a member of the notorious Al-Gebra movement. He did not identify the man, who has been charged by the FBI with carrying weapons of math instruction.

“Al-Gebra is a problem for us,” the Attorney General said. “They derive solutions by means and extremes and sometimes go off on tangents in search of absolute values. They use secret code names like “X” and “Y” and refer to themselves as “unknowns,” but we have determined that they belong to a common denominator of the axis of medieval with coordinates in every country. As the Greek philanderer Isosceles used to say, “There are three sides to every triangle.”

When asked to comment on the arrest, President Obama said, “If God had wanted us to have better weapons of math instruction, he would have given us more fingers and toes.” White House aides told reporters they could not recall a more intelligent or profound statement by the President, and it is believed that the Nobel Prize for Physics will follow.

Here we are concerned with making an inference about a population proportion consisting of two categories(like Success or Failures, Pro-Villar or Anti-Villar) from data obtained in a sample of size .

The null hypothesis is that the population proportion .

Mean and variance of sample proportion

From the binomial distribution, we know that the mean would be and the variance is

In terms of counts X, the mean is and the variance is .

An estimate obtained from a sample of size $n$ would be denoted by p (computed as X/n where X is the number of successes).

Standard error of estimated p

The standard error or standard deviation of the estimate of proportion is given by

The normalized test statistic.

Assuming n is large enough, the normal approximation can be used and the test statistic would be given by

In terms of counts, it is

Confidence Intervals for population proportions.

Let be the critical value(s) according to the level of significance . For example the lower and critical critical values for a two sided test at the 5 percent level of significance is -1.96, and 1.96 but is 1.64 for a right single sided test.

Then for a two-sided test, we accept depending on whether or not respectively.

For convenience, here are the acceptance regions or intervals for various common values of .

	left sided test :	double sided test:	right sided test:
0.01	[-2.36, )	[-2.58, 2.58]	(, 2.36]
0.05	[-1.64,)	[-1.96, 1.96]	(, 1.64]
0.10	[-1.28, )	[-1.64, 1.64]	(, 1.28]

The p-value of the test.

Suppose that we obtained the sample proportion p. Convert this to a test statistic . Then the p-value would be given as

Condition	Formula
	)
	)

Here pnorm() is the area from () using the standard normal distribution. The double-sided test would have a p-value twice the p-values obtained for the single-sided tests.

The margin of error

The confidence interval corresponding to confidence level coefficient is centered on p, and has upper and lower confidence limits of where se is the standard error of the sample proportion. The margin of error is .

Had a tough time sorting out the latex problems! It basically involves the ‘<‘ sign inside latex formulas. changed it to \le so the html display would be all right.

The second week of topblogs starts.

March 10, 2010

Our third day of reporting the topblogs results. We have our results early since we have no class.

March 9, 2010
Here is the second day of topblogs rankings for the week ending March 14, taken at around 12:00 High noon.
The brightest performer for the week, with a jump up 7 ranks is keeping math simple and challenging

March 8, 2010
Here is the latest March 8 rankings taken at around 12 High noon.

I have Chrome, Firefox and Opera in my ACER 4520 laptop which has been serving me as my desktop for a long time already. I don’t pay much attention to the speed since most are fast enough for my needs though Chrome feels faster. I prefer Firefox due to its addins ecosystem. For example the webdeveloper addin will help anyone about the design and structure of a web page.

I read something about Swiftfox which promises to be a light build of the Firefox browser. I downloaded from Get Swiftfox!, let gdebi install it and from the Applications/Internet menu clicked on Swiftfox.

Note that Swiftfox is a 32 bit application even if you downloaded the 64 bit version for Linux.
The only gripe I have is that Swiftfox still looks like Firefox when both are active. You can distinguish between the two since Swiftfox text replaces Firefox. There should be significant differences in how it looks. As for speed, Frankly I have to spend more time with Swiftfox.

Readers, have you tried this out? Tell us your experiences.

Swiftfox has a serious problem. It tells us that there is a missing plugin (Adobe flash player) , tell us that the latest Adobe flash playerer is already installed and then it repeats the whole thing!

Here is a damn good site to visit for those concerned about sharing messages that you are OUT of the house! We include a snapshot of a part of the page.
