Square Trade reports on Xbox failure rates...

23.7% of consoles repaired was 16k right? 23.7% error rate, and 16k consoles were repaired right?
100/23.7=4.24 or something. so, multiply 16k by that and you get the total consoles... unless werekitten is right and 16k is the total number of consoles they cover.

@werekitten
wow....wow....wow....no such thing as setting an equation to 0.... just wow

so whats 5x+12=0? I'll tell you... it's setting an equation to 0. That is algebra, which is based on variables like x,y,z and others.

because there are some unknown variables, like the customers who sent their consoles to MS, you can use a variable to figure it out partially.

Basically there is a 23.7 fail rate on consoles which they've covered AND repaired.
They said it could be as high as 34 or something, so that's an additional 11% or so of the total number.
Then there is also customers who didn't tell ST at all about the failure and sent it to MS automatically.

But like I said before, this problem will actually require statistics to find a distribution range over the 34. Since they haven't said anything about their math, it's especially difficult, because they might have gotten that number from standard distribution already, which would mean that if I made one, it would be completely worthless.

It's not difficult, I just don't feel like doing it. It's tedius

No to some of your assertions.

The total number of consoles reparied were 16000

Out of all the consoles covered by Square Trade the 360 has a 23.7 failure rate, the Wii a 2.7 failure rate, and the PS3 a 10 failure rate.  You can form a relational quation based the 9Xbox + 4 Ps3 + 1 Wii equal the 16000 failures.  That's a 3 unknown variable problem, and if you can solve that without calculus and Diff Eq. more power to you.  Maybe I'm missing something, but I didn't see any other data points.  But we are going down a math rathole...

The key statistical data points are:

- M$ started the 3-yr RROD repair effort in July 2007...and the number of reported RROD cases to Square Trade didn't drop, instead it when up.

- Likely, based on the data, the RROD problems are abating as the newer Jasper chipsets hit the market, and if you remove RROD, 360 has a failure rate on par with PS3...ofcourse that like saying if I was 6' 5", and If I could shoot like Ray Allen, and I could dunk like Vince carter, and play defense like dennise rodman, I'd be in the NBA right now...lol.
