Hi, i'm david and i'm here to help you answer your question.

Now let me bring up your question here in this question here we're going to review about the correction coefficient completed by hand we know that the r equal equal to the sample size n times the summation of the x times y minus summation on the x times summation under y d dividing by the square root of the first one will be the n times summation of the x square minus summation on the x totally square the second one will be the same thing but will be on the y now and then in this question here we've given the list of the data where we have the x and the y the value will be we have the two four six six and seven for the x for the y will be the four eight eleven twelve eighteen and then and we have one, two, three, four, five, one, two, three, four, five.
01:11
And that will be the dataset we have.
01:14
Now look at the formula, we need to find the sum of the x, sum of the x square, sum of the x, some of the y, some of the y, some the y square.
01:26
So i will pass the data into the calculator to find those quantity.
01:31
So i will have the value of the, so we have the two, four, and then we have the four, eight, then we have the six, eleven, six, twelve, and then seven, eighteen...
