Father's Son's height height 73.6 76.5 69.0 69.1 73.6 74.9 66.7 68.8 70.1 73.3 72.3 71.9 X Send data Use the P-value method to test H: B. = 0 versus H:, > 0. Can you conclude that father's height is useful in predicting son's height? Use the a=0.01 level of significance and the TI-84 calculator. Part 1 of 4 Compute the least-squares regression line for predicting son's height (y) from father's height (x). Round the slope and y intercept values to at least four decimal places. Regression line equation: = 0.98343X + 2.7077 Part: 1/4 Part 2 of 4 Compute the P-value. Round the answer to at least four decimal places. P-value =
