What percentage of the variation in calorie intake is explained by the regression model? Answer either in percentage or as a decimal (eg: 85.25%, or 0.8525)
To determine the influence of running before breakfast (in minutes) on calorie intake (in calories), a survey was conducted on randomly selected six persons. Running 25 35 28 18 43 50 time (x) Calorie intake 210 285 225 |215 305 355 (у) a. Determine the slope coefficient B for the regression of running time on calorie intake. Answer rounded to two decimal places. b. Determine the y-intercept a for the regression of running time on calorie intake. Answer rounded to two decimal places.
