If r‐represent the correlation coefficient between age and weight and N is the number of subjects. The calculated value of r = 0.510 and N = 15. The table value of r under column 0.05 is 0.514 and 0.01 is 0.561 for N - 2(=13)df. Then which of the following will be correct?
1
There is a siginificant correlation between age and weight at 0.01 level
2
There is a significant correlation between age and weight at 0.05 level
3
There is no significant correlation between age and weight
4
Null hypothesis is rejected
