Hi, i'm david and i'm here to have you and see your question.
00:03
In the question here, we are going to discuss about the linear regression.
00:08
I'm the form white heart equal to the y intercept b0 plus the b1 slot 10 when the formula for the y intercept on the b0 it will equal to the y bar minus b1 time with the x bar and from the slop, p1, it will equal to the n times summation of the xy minus summation of the x times summation of the y, divided by the n times submission of the x square minus summation of the x totally square.
00:45
Now in your question we're given the data for the number of the tweet and the number of attempts.
00:51
So let me combine your question and i put it on the right here.
00:57
And here we want to find the linear discussion to predict the y, where we have here the number of the teachers ' success given to each and average number of the time necessary for each to learn to perform the trick.
01:15
So here i want to find the linear discussion for the x, it will be the number of the treat, so this will be the x and this will be the y.
01:27
And look at the formula, we see that we have to find the quantity on the n, the quantity on the summation of the x, the quantity summation of the x, the quantity summation of the x square, the summation of the y, the summation of the x, now it will pass the data into the calculator...
