In the asked question, this data is the data regarding students college jbas and high school gbas.
00:12
And the estimated regression equation is given here that estimates the college gba given the high school gba.
00:22
It's required to compute the sum of squared errors for this model and round our answer to 4 decimal place.
00:30
The first step is to calculate the error.
00:33
But to find the error we should find the estimation then before getting the error we should add a new column here sorry we can add a new column here like that by getting the estimated college gba to get the estimated college gba we substitute by the value of high school gba in this equation for the first entry it's 3 .3 8 it's 2 .35 plus 0 .2, sorry, this is 0 .2, 4 .07, multiplied by 3 .38, multiplied by 3 .38.
01:26
It gives 3 .163 -566.
01:31
We should work of 5 or 6 decimal place to get our final answer accurate 4 decimal place.
01:41
The second entry is 4 .45.
01:45
We substitute here it's 2 .35 plus 0 .2407 multiplied by 4 .45.
01:54
It's 3 .421115.
01:59
Again, we substitute by 3 .76.
02:03
It's 2 .35 plus 0 .2407 multiplied by 3 .76.
02:05
It equals 3 .25 plus 0 .2407 multiplied by 3 .76.
02:10
It equals 3 .25...
