Before these can be determined, some preliminary algebra is necessary. x, y, x2,
xy, (x)2, (y)2, n, y, and x need to be determined.
17. x = 1.831 + 1.631 + 1.451 + 1.264 + 1.119 = 7.296
18. y = 52.06 + 47.05 + 42.05 + 37.04 + 33.04 = 211.24
19. x2 = (1.831)2 + (1.631)2 + (1.451)2 + (1.264)2 + (1.119)2 = 10.96798
20. y2 = (52.06)2 + (47.05)2 + (42.05)2 + (37.04)2 + (33.04)2 = 9155.7518
21. xy = (1.831)(52.06) + (1.631)(47.05) + (1.451)(42.05) + (1.264)(37.04) +
(1.119)(33.04) = 316.865528
22. n = 5
23. x = x/n = 1.4592
24. y = y/n = 42.248
25. (x)2 = (7.296)2 = 53.231616
26. (y)2 = (211.24)2 = 44622.337
