Hi, i'm david and i'm hachahab.

You answer your question.
00:02
In this question here, we're given a table of the price in dollar and the number of the bit.
00:09
And let me bring up the data here.
00:13
And from the data here, i want to predict the number of the bit based on the list price.
00:20
So it means that the price will be the x and the number of the bit will be the y.
00:25
And we want to formulate the linear question on the form yhat equal to the b0 plus the b1, times in the x and the question asked you find the one intercept we know that the intercept it will be equal to the b0 and it will equal to y bar minus the b1 times in the x bar so we need to find the b1 first and the b1 will be the slump it will equal to n times summation the x y minus summation the x times summation the y divided by the n times summation the x square minus the summation the x totally square.
01:06
Now with the data set, we will be able to find the n, and then the summation of the x, the summation of the x, the summation of the x square, the summation of the y, and then the summation of the x y.

Now it will pass the data into the calculator...
