[QUOTE=Madpoo;502087]
Come to think of it, of the 16 discovered by GIMPS, half (8) were found in just the 3 months of Nov-Jan. I guess if you want to improve your odds of finding a prime, you should do more tests in the late autumn and winter. Statistics don't lie.[/QUOTE]
Care to put up a frequency table or list by calendar month? Here in Wisconsin, the 3 months you give are all solidly in the heating season.

Oh, and I've been thinking about moving the Jan 10 straggler, or twinning it. (GTX1080Ti? Dec 12.)
My other <82M assignment should finish tomorrow undisturbed.


But the 3 in [URL]https://www.mersenne.org/assignments/?exp_lo=81716699&exp_hi=82000000&execm=1&exp1=1&extf=1&exdchk=1[/URL] with the earliest estimated completion dates, haven't reported in status for weeks, and won't expire for weeks. (One expires in January. Art Lieberman, call your office.)

[QUOTE=Madpoo;502197]It's funny the things you can do that make sense statistically but have no bearing on reality. Things like "the average American has 2.4 kids" which would be terrifying if true. That's a lot of mutant kids.[/QUOTE]

Mutant, or mutilated? Ugh.

So statistically, having an exponent complete on the last Saturday of a fall or winter month looks good, and means nothing.

Is that a hint Mp#51 has been found and is in verification?
Or of prime95 v29.5 being released for production use?

I could go into the details about how you chop the third child into fifths (twice), but that might be just a little dark for this audience...

A little more relevant might be the [URL="https://en.wikipedia.org/wiki/Birthday_problem"]Birthday problem[/URL]....

A little more relevant might be the [URL="https://en.wikipedia.org/wiki/Birthday_problem"]Birthday problem[/URL]....[/QUOTE]"These conclusions are based on the assumption that each day of the year (excluding February 29) is equally probable for a birthday." I believe the assumption is flawed. In my immediate family of 6 individuals, 3 members' birthdays land in a span of 4 consecutive calendar days, consistent with a _very_ Merry Christmas or Happy New Year. Another is consistent with celebrating one of those birthdays well.

In southern Wisconsin, there was an ice storm with resultant power outages in the late 1970s. There was a distinct rise in maternity ward occupancy ~40 weeks later, corresponding to what people did to keep warm and keep from being bored during the days of cold and dark homes.

Looks like the first is the case. (It could be both.)

HA! One friend of mine who is statistician has an even better one, he use to say that "the average human has only half of a penis"....

That's a lot of mutant kids.[/QUOTE]There's the joke about the guy who has his head in the fridge and his feet in the oven (or is it [i]vice versa[/i]?), and "on average" feels fine.

One misformulation of statistical info that makes me [i]cringe[/i] is of the type, "On average, ... each ((and) every) ..." like

"On average, x number of babies are born in the US [i]each second[/i]."

"On average, x number of people die (of such and such a cause ) [i]each and every day[/i]."

"On average, there are x number of mass shootings [i]every week.[/i]"

Just imagine: "On average, [i]each and every[/i] American family has 2.4 kids..."

Talk about a lot of mutant kids!
