Question 2 a.The slope of the regression equation and the correlation r are equal only when The SD of both X and Y are 1 "' X and Y are converted to Z soores The SD of); and Y are the same Submit Answer Tries Of 1 b. Suppose you increase your sample size from 25 to 100, how will that change the SE for slope, assuming all else is equal? It will be be divided by 2 "' be divided by 4 be multiplied by 4 be multiplied by 2 Submit Answer Tri es Op'2 c. Suppose you know the SE of the slope for n=25. How would you change that to calculate 5E+? multiply by sqrt(23) " multiply by 2325 ' ' multiply by sqrt(23f25) multiply by sqrt(25f23) multiply by 25/23 Submit Answer Tries 0/2 d.
