Research was conducted on the amount of training for 5K and the time a contestant took to run the race. The researcher recorded the number of miles during training ( a 1 month period) and the time to complete the 5K. The results are below.
Miles Trained | 48 | 47 | 38 | 79 | 51 | 77 |
Time (Minutes) | 23.9 | 26.1 | 35.7 | 19.6 | 28.5 | 18.6 |
a) Give the correlation coefficient. r = b) Give the equation of the regression line. Round the values to 4 deimal places. This is in the form y = ax + b, so the slope goes in the first box and the y-inercept in the 2nd box. y = x + c) Predict the time in the 5K if someone trained 38 miles. Use the rounded values entered for the slope and intercept of the regression line to compute the predicted y-value. y = d) Give the residual for 38 miles trained. This is the actual y value for the runner who trained for miles minus the predicted value. Residual=
