I keep plugging this into the calculate but it's giving me the wrong answers. I don't know what I'm doing wrong

In the previous step we verified the following summations. W x = 441 Zy = 274 S'x2 = 32,659 WWW yz = 12,644 xy = 20,283 Now, noting that the sample size is n = 6, we can calculate the value of r to six decimal places using the following formula. " [ xy - ([ * ) ( Ex) r = 6(20,283) - (441)(274) 11 32659 - (441)2 12644 1- (274) 2 864 = V 1473 This verifies the approximate value of r
