Hey everyone in this question we have the table and we have to find out the values of c.
00:07
Okay, so now we submission, we put the same value of submission that is sigma x is equal to 27 .3, sigma y is equal to 17 .4, sigma xy is equals to 77 .16 and sigma square is equals to 112 .45 and sigma log y that is equals to 1 .661.
00:28
We simply put the values of these and now we're fitting straight lines by least square.
00:34
Now we fitting straight line by least squares.
00:39
So we have the equation y is equal to a x plus b.
00:43
We have the equation by least squares.
00:48
So we have the equation y is equals to a x plus b.
00:54
Y is equals to a x plus b and sigma y is equal to a x plus b.
01:00
X plus n into b this is a second equation and third is third one is sigma xy is equals to a sigma x square plus b multiply sigma x so this is a third from second and third we have the equation sigma y is equal to a of sigma x plus n into b so we here put the values of sigma y sigma x and b so we have the value of sigma x y that is equal to so this is the fourth equation and we have the equation sigma xy is equal to a of sigma x square plus b of sigma x.
01:39
So here we put the all values and we have to calculate the value of a, b and c we have to calculate the constants...
