In a test to determine if r is statistically significant, H1 is.
A)r = 0
B)r = 1
C)ρ ≠ 0
D)ρ = 0

Question

Quizplus · Accepted Answer

H1 refers to the alternative hypothesis and it should state that the correlation coefficient (r or ρ) is not equal to zero, indicating a relationship between the two variables being tested. Therefore, the best choice is C, which states that ρ ≠ 0. Options A and D incorrectly state that the correlation is zero, while option B indicates a perfect positive correlation, which may not be the case in reality.
