Suppose that data are obtained from 50 pairs of (x, y) and the sample correlation coefficient is 0.50. (a) Test the hypothesis Ho:p = 0 against H:p # 0 with a = 0.01. Calculate the P-value. Round your answer to three decimal places (e.g. 98.765). the hypothesis Ho:p = 0. P-value= i (b) Test the hypothesis Ho: p = 0.6 against H:p # 0.6 with a = 0.01. Calculate the P-value. Round your answer to three decimal places (e.g. 98.765). the hypothesis Ho: p = 0.6. P-value= i (c) Construct a 99% two-sided confidence interval for the correlation coefficient. Round your answers to three decimal places (e.g. 98.765).
