Question

Which of the following is an example of a null hypothesis for testing a correlation coefficient? A)H₁: $\rho$_xy = 0 B)H₁: $\rho$_xy > 0 C)H₀: $\rho$_xy = 0 D)H₀: $\rho$_xy > 0

Quizplus · Accepted Answer

The null hypothesis for testing correlation coefficient is that there is no significant relationship between the two variables being tested (i.e. correlation coefficient = 0). Option C is the only one with this hypothesis stated. The other options suggest that there is a positive correlation, which would be an alternative hypothesis, not the null hypothesis.
