The regression equation Y-bar = 3,698 + 2,538X gives an R2 value of 0.2645. This means that ________. Q. Which one is true? 1. the percentage of variation in Y that is attributed to random factors is 26.45% 2. X and Y have a very high level of correlation 3.26.45% of the variation in Y can be explained by X

Solution

The r^2 value says the percentage of variation in y that can be explained by x. Hence, it is

OPTION 3: 3.26.45% of the variation in Y can be explained by X. [ANSWER]
