Five observations takon for twa variables foliow. (a) Develoo a scatter dagram loe these data (b) What does the scatter diagram indicate about the relationship between x and y ? The scatter diagram indicates that there is linear relationship between the two variables. (c) Compute the sample covariance. Interpret the sample covariance. The sample covariance indicates that there is linear relationship between the two variables. (d) Compute the sample correlation coefficient. (Round your answer to three decimal places.) Interpret the sample correlation coefficient. The sample correlation coefficient indicates that there is linear relationship between the two variables..
