Hi! I am stuck on these 2 multiple choice questions I have in my homework. I do not understand r or what its exactly asking for.Thank you for any help!

Question 2 (1 point) If you have a large value of r, say .7 or greater, then you can conclude O A) that 70% of the variability of Y is explained by X. (B) that 70% of the large X scores will have large Y scores. O C) that X and Y have a large positive linear relationship. ( D) that X causes Y. Question 3 (1 point) Researchers compute the coefficient of determination (i.e., ?) to: A) determine if the correlation is positive or negative. ( B) determine the amount of shared variance for a non-significant r value. C) assess the amount of error in a statistical test. ( D) assess the linear characteristic of the correlation. (E) determine the amount of shared variance for a significant r value
