Hello, friends, welcome.
00:03
We have a question here and this question is about some students and their gpa which is grade point average and at scores.
00:18
So this is given as a table 1, 2, 3, 4, 5, 6, 7 and 8 observation into the portion and we have 2 .8, 1st 30, 4, 5, 6, 7 and 8 observation into the portion and we have 2 .8, 1st 30, 4, 4 ,000, 7, 8, 1 ,000, 1, 1, 3 ,000.
00:33
Then 3 .0 and after that 3 .5.
00:37
3 .6, 3 .0, then 2 .7 and last is 3 .7.
00:46
And for act score, we have scored as 21, 24, 26, 27, 29, then 25, 25 and 30 respect.
01:01
So this is our table into the question and now we have to solve some question over.
01:05
Over here so first of all we have to solve the values related to the table here so we'll solve your value of b -o this way and b -o so these respective values will be i'm writing over here for first reading will be 58 point 8 and 8 1 .6 7 t then 9 .4 .5, one zero four point five, and next is 76, just to make, let me tell you.
01:59
I have first various, 48 .8, next is 81 .6, next is 78, then you have 949, 94, 76, and 6.
02:15
Just don't make, this value is wrong.
02:19
Okay so there we will have 76 and now next value it is 67 .5 then we have triple one we'll stop with one value over here this is seven these are the values and now we'll find the next follow next following would be square of 21 is 441 square of 241 square of 24 is 576 then next is the square of 26, which is 670.
02:57
6 square of 27 is 729.
03:00
Square of 29 is 841, square of 25 is 6 to 5.
03:06
Again 25, so 6 to 5.
03:09
And then we have 30, so 9.
03:12
And our last column will be the releasing column.
03:17
So we will have the building as you have to divide these two values and the column will be as follows 7 .84 next will be 11 .56 next will be 9 and after that we have 12 .75 then again 9 and 7 .2 just a minute 9 where we have the value is 12 .75 96 .96 then next value is 9 after that we have 7 .29 then last is 13 .16 9 so these are the value into the table so let's find out our next which is y cap is equal to in o cap added by 1 meter 1 x so beta 1 cap will be equal to it's yxxxxxxxxx will be equal to it's y upon xx and the value for beta not is equal to y minus one beta 1 x bar so let's find out the value here for m one cap the one cap is a summation of x i y i minus n x bar y bar divided by submission of x i squared minus n x square minus x so here x bar will be equal to 1 upon n submission of x i which is 207 and value of n into the denominator after solving this we will have 25 .875 and value of 5 will be equivalent and value of 5 will be equipped to 3 .2125.
05:33
So let's calculate from these values value of 2.
05:41
Beta 1.
05:43
Meta 1 cap is equal to 670 .8 minus 8 ingo 25 .875 multiplied by 3 .2125.
05:56
All the values we have find in the previous page.
06:01
This is 541 .13.
06:03
Minus 8 multiplied by 25 .875...
