00:07
In the question here, we are going to discuss about the correction coefficient r.
00:11
We have the formula r, it will equal to the n times summation of the xy, minus summation of the x, times summation of the y, given by n times summation on the x square minus summation the x totally square.
00:27
We do the same thing on the y, n times summation in the y, 2nd, 2nd, square, and the y totally square and then we turn the square root on the denominator.
00:37
Now we are given the list of the cost and the number data.
00:42
From here we first we see that one, two, three, four, five, six, seven, eight.
