Your solution is correct. I overlooked a small point which made my solution wrong.

Comment on The Value of Statistics? by The Crunger http://genew.ca/the-value-of-statistics/#comment-14840 Sat, 23 Jul 2016 02:02:16 +0000 http://genew.ca/?p=3003#comment-14840 I think a look at Alexa’s rank for India would make it clear. http://www.alexa.com/topsites/countries/IN

Google (india) gets the most Indian traffic, where as regular Google.com is #2 in India. Yet, Google.com gets more world-wide traffic than any site — perhaps 1000s of times more than the site that “beat” them looking at the restricted pool of Indian traffic.

Comment on Puzzle #160 Solution: Oops! by Gene Wirchenko http://genew.ca/puzzle-160-solution-oops/#comment-14774 Wed, 06 Jul 2016 03:13:20 +0000 http://genew.ca/?p=3057#comment-14774 Nope. Would the probability of making exactly one error in 100 weeks be 100%? Would the probability of making exactly one error in 200 weeks be 200%? The probabilities do not add in this case. Look up the birthday problem: how many people (selected randomly) are needed to have at least 50% probability that at least two of them will share birthdays? The answer is lower than you almost certainly think (if you have not seen this problem before).

Comment on Puzzle #160 Solution: Oops! by Lynne Mugford http://genew.ca/puzzle-160-solution-oops/#comment-14755 Wed, 29 Jun 2016 20:50:56 +0000 http://genew.ca/?p=3057#comment-14755 Could this be another oops? Shouldn’t the percentage be greater than 10 %? Since the probability of making an error is 1 %, the probability of making exactly one error in ten weeks should be 10 %?

Thanks,

Lynne

If they are 1,764th in the world, where are the sites that push them down to 2,389th in the U.S.A.? Are those additional sites not in the world?

If they are using different pools of traffic, what are those pools? Where is this stated?

Comment on Odd Language #156: Used To by The Crunger http://genew.ca/odd-language-156-used-to/#comment-14653 Wed, 15 Jun 2016 00:30:28 +0000 http://genew.ca/?p=3022#comment-14653 The expression is somewhat ambiguous since we don’t see whether it is present-tense “These are used to …”, or past-tense “These were used to …”.

(Murrican) English is my first language, and the present-tense interpretation seems much more likely, without additional cues in context. If the sentence/paragraph read “Used to , but now .”, then the past tense intention might be assumed.

* I see no conflict in Alexa ranking their own website, so long as they apply consistent criteria to data collected even-handedly. Google has to pagerank its own pages, and those of its partners, with litigation as a check against any “thumbs on the scales”.

* Also, I see no conflict in Alexa having a better “worldwide” ranking than a ranking in their own country, since these are based upon different pools of traffic. Sites that are quite popular in their own country may do much more poorly worldwide, while sites that get most traffic from out-of-country might not rank so well in their own home country … as is the case with Alexa itself.

Comment on Not the Big Time by Gene Wirchenko http://genew.ca/not-the-big-time/#comment-14520 Tue, 07 Jun 2016 01:56:39 +0000 http://genew.ca/?p=3016#comment-14520 I had to read that first paragraph a second time before I caught on.

My mom had a male Chinese herbalist named Jude.

If you would answer the phone, it would help with paragraph 2. Of course, you will not. (I have never seen the word “curmudgeon” used to describe a female, but a quick check at dictionary.com reveals that it is not just for males. Enjoy!)
