Okay, so we've got that the predicted value of education is given by that regression equation there.
00:06
Now, the first part says, does sibs have the expected effect? and i would say that we would expect that only if you had a very large number of siblings, siblings, might it affect how many years education you have? because, for example, parents might not be able to afford it or manage for that many people to be educated.
00:45
But all the parents might be less attentive, less around, because they're busy working or whatever.
00:51
But if you've got a sort of a small number of siblings, you wouldn't really expect it to affect that much.
00:58
And we're but also asked how many siblings would you have to have in order to decrease the years of education by one? that is just we want minus 0 .094 times some number of siblings x to equal minus one.
01:14
And if we solve for that, we find that x is equal to 10 .64.

For part two, then it says discuss the interpretation on the coefficient of m education...
