Hi, i'm david and i'm here to have you answering your question.
00:03
Now let me bring up your question here.
00:06
In the question here, we are going to discuss about the linear question.
00:11
Let me remind you that the formula will be the white heart equal to the b0 plus the b1 terms of the x, where the formula for the b0 equal to the y bar minus the b1 times in the x bar.
00:23
The formula for the p1, it will equal to the correlation coefficient r, terms of the standard level, of the y over the standard error of the x.
00:33
In the equation here we are told that we have x will be the mid term and the y will be the final exam score and we're given that the x bar equal to the y bar and equal to the 77 and also the standard division of the x equal to the standard division of the y and equal to eight and we're given the all equal to the 0 .66 therefore, we should be able to find the p1 or equal to the 0 .66.
01:07
Sy equal to the 8 over the xx also equal to 8 and then we get equal to 066.
01:14
We plug this value into this to find the p0, y power we get equal to the 77, and then minus p1 will be the 0 .66, x -par equal to the 77.
01:30
And then we get the answer equal to the 26 .18.
01:40
Then we have the linear equation why hot equal equal to the 26 .18 plus what that be 1 will be the 0166 times the x...
