Answer #1

	X	Y	X*Y	X²	Y²
	3	15.8	47.4	9	249.64
	4	15.7	62.8	16	246.49
	5	15.9	79.5	25	252.81
	6	15.6	93.6	36	243.36
	7	16.4	114.8	49	268.96
	8	15.7	125.6	64	246.49
	9	16.1	144.9	81	259.21
Total	42	111.2	668.6	280	1766.96

η = ((N + ΣΧΥ) - ΣΧΣΥ)/ (ΝΣ(Χ2) - (ΣΧ)2) (ΝΣ(Y2) - (ΣΥ)2)

=4680.2-4670.4 / rt(1960-1764)(12368.72-12365.44)

=0.386
