Please explain your answer and help me understand the concepts. Thanks

After I ran a regression between Exercise Time in minutes (X) and calories burnt (Y), I got the coefficient for the Intercept as 50 and the coefficient for Exercise time as 5. The following is then true For each minute of exercise done the person burns 5 less calories. The regression line is then given by: Calories burnt = 50 + 5 (Exercise time) The slope of the regression line is 5 and the y-intercept is 50. For each minute of exercise done the person burns 50 less calories. According to the equation, a person who does not exercise (zero minutes of exercise) still burns 50 calories. This is not meaningful and it is probable that "0 minutes" was not part of the sample data. The regression line is then given by: Exercise time = 50 + 5 (Calories burnt) The slope of the regression line is 50 and the y-intercept is 5. For each minute of exercise done the person burns 50 more calories. For each minute of exercise done the person burns 5 more calories.

Explanation / Answer

here regresson equation is Y=mX+c ; where Y is calories burnt , X is excercise time. m=slope and c=y intercept

therefore equation from above data Y =5X+50

1)false; as for Y is proportional to X,from above equation, person burn 5 more calories for each minute of excercise.

2)true as given above

3)true

4)false, only 5 calories and more

5)true

6)false as does not match with equation

7)false; slope is 5,

8)false

9) true
