Answer 1

In hypothesis testing, the population parameter for the correlation coefficient is represented by:

option D. r

Which of the following would indicate the strongest relationship between two variables?

a. 0.81

for the fiven options 0.81 indicates the strong postive and also the straight line linear relationship between the variables.
