According to the given table, if we consider a table which contains x, y, x -x bar, y -y bar, x -x bar whole square and x -x bar into y -y bar, 112, 125, 115, 136, 143, 116, 123, 124.
00:33
Now, y values are 70, 89, 65, 90, 97, 64, 78 and 69.
00:47
X -x bar values are given as minus 12 .25, 0 .75, minus 9 .25, 11 .75, 18 .75, minus 8 .25, minus 1 .25, minus 0 .25.
01:11
And y -y bar values are given as minus 7 .75, 11 .25, minus 12 .75, 12 .25, 19 .25, minus 13 .75, 0 .25, minus 8 .75.
01:35
Now, x -x bar whole square values are given as 150 .0625, 0 .5625, 85 .5625, 138 .0625, 351 .5625 and 68 .0625, 1 .5625 and 0 .0625.
02:11
X -x bar into y -y bar values are given as 94 .9375, 8 .4375, 117 .9375, 143 .9375, 360 .9375, 113 .4375, minus 0 .3125, 2 .1875.
02:54
Now, sigma x is given as 994 and sigma y can be given as 622.
03:09
Now, x -sigma x -x bar whole square can be given as 795 .5 and sigma x -x bar into y -y bar can be given as 841 .5.
03:32
Now, x bar is equals to sigma x by n that is equals to 994 by 8 is equals to 124 .25 and y bar is equals to sigma y by n that is equals to 622 divided by 8...
