Question

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 one-sided alternative H₁ : ρ > 0.To test H₀ : ρ = 0 against the two-sided alternative H₁: ρ ≠ 0 at a significance level of 0.1,the p-value is A)0.256 / 2. B)(0.256)(2). C)1 - 0.256. D)1 - 0.256 / 2.

Quizplus · Accepted Answer

For a two-sided test, the p-value is double the one-sided p-value.

The Sample Correlation Coefficient Between X and Y Is 0
