Question

Questions 6 to 10 are based on the problem below: Compute the Pearson Correlation Coefficient, r, for the following data X Y 2 3 3 1 6 5 4 4 5 2 The Pearson Correlation, r is: Group of answer choices r = 0.43 r = -0.87 r = 0.5 r = -0.72 Flag this Question Question 7 4 pts The correlation is Group of answer choices Medium and negative Large and negative Large and positive Medium and positive Flag this Question Question 8 4 pts The null hypothesis in symbols for a two-tailed test is Group of answer choices H0: r = 0 H0: ρ ≠ 0 H0: ρ = 0 H0: r ≠ 0 Flag this Question Question 9 4 pts If we use a two-tailed test with α = .05, the critical r values are: Group of answer choices ±0.754 ±0.959 ±0.805 .±0.878 Flag this Question Question 10 4 pts Your decision is Group of answer choices Reject the null hypothesis and conclude that there is a significant correlation between X and Y Fail to reject the null hypothesis and conclude that there is a significant correlation between X and Y Reject the null hypothesis and conclude that the correlation between X and Y is not significant Fail to reject the null hypothesis and conclude that the correlation between X and Y is not significant
