Here, we will take vitamin c content as a function of the weight of the respiratory.
00:11
So weight here we have, the weight here we have, it's taken as on x and vitamin c content, this taken as y.
00:19
We want to find a linear model, also make a table here to find out x into y, x square, y square.
00:24
So let's find out that.
00:27
Find out the value in x into y, we get this column, x square we get this column, y square we get this column.
00:34
Now to find a sum here, some of each column, so we'll have the sum that is given as positive 630.
00:47
Next sum is given as 193 .4.
00:52
You can calculate it.
00:54
Next is 1 -745 .5.
01:01
Next sum is 574 -0.
01:06
Next sum is 5508 .2.
01:16
.24.
01:17
And next, we'll calculate here this quantity that is given as 1 over n.
01:25
Summation x y that is x bar summation x i equals 1 to n sum is given as 630 here for x so 630 4 divided by 7 right that gives 90 so you'll find out y bar that is given as 193 .4 all divided by 7 that is given as 27 .6287 6287 6287 round the other places i'm taking here.
02:11
Let's sum of squares for xx that is given as summation xi square, i equal 1 to n.
02:27
Negative we have 1 over n summation xi equal to 1 to n square.
02:40
We have some of squares for xx.
02:43
It is given as this is 57 4 .0.
02:50
X i square here we have so 57 4t0 right negative 1 over 7 193 .4 square 1 and 3 .4 that we do so it will get 164 .87 164 .864 .87 4 to 9 it will give this next sum of squares for xy let us give an summation i equal to 1 to n xi yi negative 1 over n summation x i summation y i commission x i my i then look at table one double seven 4 5 point 0 .5 negative look at table 630 times 103 .4 divided by 7 and we'll give 239 .5 339 .5 on the other calculations we find out now, the slope m and the y intercept n.
04:38
So slope m is given as sum of squares x y over sum of squares x x.
04:48
So do the sum of two to be 3, 9 .5 over 700...
