Considere um modelo de regressão linear simples na forma Y = aX + b + ε , em que ε representa o erro aleatório com média zero e desvio padrão σ, e a variável regressora X é binária. A média amostral e o desvio padrão amostral da variável explicativa Y foram, respectivamente, iguais a 10 e 4. Já para a variável regressora X , encontra-se a distribuição de frequências absolutas mostrada no quadro a seguir. Finalmente, sabe-se que a correlação linear entre Y e X é igual a 0,9.

In May 2021, a hole was found in a robotic arm aboard the International Space Station (ISS). The suspected culprit was a piece of rogue space junk. While thankfully no astronauts were injured, it has re-focussed attention on the growing problem of orbital debris.

How did we get here?
..
It’s easy to forget that just seven decades ago the Moon
was the only thing orbiting the Earth. On 1 January 2021 there
were 6,542 satellites in orbit. Tellingly, only just over half of
them were active. That’s a lot of useless metal careering around
the planet at 28,000 kph — ten times faster than a bullet.
...
How bad is the problem?
..
Very bad and getting worse. Estimates suggest there are
currently half a million pieces of debris the size of a marble or
larger and 100 million pieces of debris above one millimeter
across. Yet only 27,000 pieces are actively tracked by the US
Department of Defense.
..
What is Kessler syndrome?
..
It’s a catastrophic chain of events in which a satellite is
shattered by a piece of space junk (or a collision with another
satellite) and the resulting debris destroys more satellites creating
more junk and so on in a never-ending cascade. It’s a domino
effect – one piece falls and then takes the rest with it – and is
named after NASA scientist Donald Kessler, who outlined the
dangers back in 1978.
...
What can we do about it?
..
Better regulation of new launches would help, as right
now it’s a bit of a free-for-all. There are existing regulations in
place to try and mitigate the dangers, such as a 25-year de-orbit
rule for missions in low-Earth orbit. However, ESA’s Space
Debris Environment Report says that less than 60 per cent of
those flying in low-Earth orbit currently stick to the rules.

Early electronic computers such as Colossus made use of punched tape, a long strip of paper on which data was represented by a series of holes, a technology now obsolete. Electronic data storage, which is used in modern computers, dates from World War II, when a form of delay-line memory was developed to remove the clutter from radar signals, the first practical application of which was the mercury delay line. The first random-access digital storage device was the Williams tube, based on a standard cathode ray tube, but the information stored in it was volatile in that it had to be continuously refreshed, and thus was lost once power was removed. The earliest form of nonvolatile computer storage was the magnetic drum, invented in 1932 and used in the Ferranti Mark 1, the world’s first commercially available general-purpose electronic computer.
