question 115

Multiple Choice

When testing whether the correlation coefficient differs from zero, the value of the test statistic is t₂₀ = 1.95 with a corresponding p-value of 0.0653. At the 5% significance level, can you conclude that the correlation coefficient differs from zero?

• A) Yes, since the p-value exceeds 0.05.
• B) Yes, since the test statistic value of 1.95 exceeds 0.05.
• C) No, since the p-value exceeds 0.05.
• D) No, since the test statistic value of 1.95 exceeds 0.05.
