Question 17,

You are given the following sample data for two variables:

The sample correlation coefficient for these data is approximately r = 0.755.

Y	X
10	100
8	110
12	90
15	200
16	150
10	100
10	80
8	90
12	150

Hence r=0.755 is true.

X	Y	XY	XX	YY
100	10	1000	10000	100
110	8	880	12100	64
90	12	1080	8100	144
200	15	3000	40000	225
