Test the claim that the linear correlation coefficient of a population is statistically significant. A random sample of 15 (x,y) pairs yields r = 0.51. Use a = 0.05. 1. Select the correct statement: O If the correlation is found to be statistically significant, that means that changes in x cause changes in y O Even if the correlation is found to be statistically significant, that does not necessarily mean that changes in x cause changes in y The hypotheses are: Ο Ho:ρ-0; Ha: ρ 0 O Ho:r = 0; Ha:r0 O Ho:r 0 O Ho:r > 0; Ha:r 0; Ha:p 0 2.
