Okay, in your question, it says part one, given a regression equation of y hat equals 16 plus 2 .3x, the question is, if x increases 2 .0 units, that that would lead to an average increase of y of 4 .6.
00:20
So basically what we're saying, if this goes up two units, increases two units, we would see an average increase in.
00:32
Of 4 .6.
00:34
So i'm going to i'm going to test this by just plugging a one in for x and then i'm going to increase it by two.
00:41
Actually, let's plug a zero in for x and then we'll increase it by two to two and see what our results are.
00:48
If we put a zero in, it would be 16 plus 2 .3 times 0 or 16.
00:55
If we put a 2 in, it would be 16 plus 2 .3 times 2, which would be 4 .6 added to the 16 or 20 .6.
01:07
So we did see an increase of 4 .6...
