4. A runner was tested on a treadmill. During the test, his speed x (in km/h) and his hear rate y were measured. The results are shown in the table. y 122 132 145 161 178 190 x 8 10 12 14 16 18 (a) Test for the significance of regression using the analysis of variance with a = 0.05. Find the P-value for this test. Can you conclude that the model specifies a useful linea relationship between these two variables? (b) Estimate ². (c) Estimate the standard error of the slope and intercept in this model.
