Answer:
0.9769
Step-by-step explanation:
Given the data :
X : 7.5, 9.9, 4.8, 9, 8.1, 1.7, 3.1
Y : 35, 6, 45, 18, 20, 89, 84
The Correlation Coefficient obtained by using a graphing calculator to model the data above is : 0.9769, this means a strong positive correlation exists between the two variables.
15.9
so -9.7 is 9.7 jumps form 0 and same for 6.2 is 6.2 jumps from 0
9.7 + 6.2 = 15.9
the distance between -9.7 and 6.2 is 15.9
