Exercise 14-5 Algo 6.25 A sample of 26 observations provides the following statistics: [You may find it useful to reference the t table.] points Sx = 16, sy = 24, and sxy = 119.03 a-1. Calculate the sample correlation coefficient xy. (Round your answer to 4 decimal places.) Sample correlation coefficient a-2. Interpret the sample correlation coefficient rxy The correlation coefficient indicates a positive linear relationship. The correlation coefficient indicates a negative linear relationship. The correlation coefficient indicates no linear relationship. b. Specify the hypotheses to determine whether the population correlation coefficient is positive.
