Suppose you and a friend each take different random samples of data pairs (x,y) from the same population. Assume the samples are the same size. Based on your samples, you compute r = 0.83. Based on her sample your friend computes 0.79. Is your friend’s value for r wrong? Explain

    Right or wrong cannot be judged. To find out if they are significantly different, the size of the samples needs to be know.
