Okay, so i see that you need help with this problem.
00:03
And the first question asks, the figure shown to the right contains a scatter plot of 10 data points for trees, where the diameter of the tree at the breast height is given in inches and the height is given in feet.
00:16
The regression model is shown below, where x is the dbah in inches and y is the height and feet.
00:24
So if the first question was, you know, the rate of change.
00:33
And so the rate of change is 0 .96 feet per inches.
00:40
So change is 0 .96 feet per inches because feet is on the y -axis.
00:52
So that comes first.
00:53
Okay.
00:54
What is the effect of a 1 inch increase in dba? so my equation is y equals 0 .96.
01:07
So y equals 0 .96 x plus 4 .7.
01:17
And inches is your x.
01:21
So then i would just do 0 .96 plus 4 .7.
01:33
And that equals 5 .66 feet.
01:38
So it would be 5 .66.
01:42
5 .66 foot increase in the height...
