Question 188924
n = 8 
r = 0.915931 
---
I ran a LinReg program against the x/y values and found r = 0.9159
which is sam value you found.
-------------------------------------
Using the r calculated in problem the significance of the correlation coefficient using alpha = 0.01 and the claim rho ≠ 0. 
Answer:
1. Ho : rho = 0
Ha : rho ≠0
2. alpha = 0.01
3. Find t = r/sqrt[(1-r^2)(n-2)] = (0.9159)/sqrt[(1-0.9159)^2/(8-2)]
= 5.4891
4. to = 0.834 
5. Rejection region: t > 0.834 
6. Decision: Since t > to reject Ho.
7. Interpretation: There is a linear relation between x and y.
