Hi, i'm david and i'm here to help you answer 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 regression.
00:11
Let me remind you that the formula for the y heart equal to the p0, which is the y intercept, plus the p1 times under x.
00:20
Now the formula for the p1, it will equal to the n times summation xy, minus summation of the x times summation the y divided by n summation the x square minus summation the x totally square and the formula found the p0 if we know the p1 we just again the y power minus p1 times in the x bar so now to find these two values we will need to have those quantity first will be the sum of x square and the n now and it will be easy we see there are five that are set and now to find those values i will pass the data into the calculator we have the one or two here we have to make sure which one will be the x which one will be the y here the x will be the letting the right amlet pressure be the predictor so the so this one will be the x now and so this will be the y.
01:30
Now we will have 102, 177, and then 101, 170, 94, 145, 76, 143, 77, 145.
01:51
So we will have the sum of the x equal to the 450, the sum of the x equal to the 450...
