So in this problem, we're a biologist and we're assuming that there's a linear relationship between the amount of fertilizer supplied to an apple plant or an apple tree and the yield of apples that get obtained.
00:15
And so we pull eight apple trees of the same variety and we get this data off of it where x is the grams of fertilizer dissolved in a fixed.
00:34
Amount of water going on the plants.
00:37
And then why is the kilogram yield coming off of apples off the tree? and so first we're asked to plot a scatter diagram of yield against the amount of fertilizers, x.
00:56
So we need to go into a graphing calculator or a graphing system and graph this data.
01:02
So i went to desmos .com brought down the graphing calculator.
01:07
Which looks like this.
01:10
And on this system, i can go to the plus right here and get the table.
01:15
And so then i start entering the data.
01:18
So i have one, one and a half, two, two and a half, three, three and a half, four, four and a half.
01:29
And then the y at one is three point nine.
01:35
The one and a half is four.
01:39
That two is five point eight.
01:47
At 3 is 7 .0, at 3 .5 is 7 .1, and 4 is 7 .3.
02:06
Got off somewhere didn't i, 5 .8.
02:08
This is supposed to be 6 .6, isn't it? 6 .6, and 7.
02:16
And then 7 .1, and then 7 .3.
02:24
And lastly, 7 .7.
02:28
So there's the data...
