question 72

Multiple Choice

The sample correlation coefficient between X and Y is 0.375. It has been found out that the p-value is 0.256 when testing H₀ : ρ = 0 against the two-sided alternative H₁ : ρ ≠ 0. To test H₀ : ρ = 0 against the one-sided alternative H₁ : ρ < 0 at a significance level of 0.2, the p-value is

• A) 0.256/2.
• B) (0.256)2
• C) 1 - 0.256
• D) 1 - 0.256/2
