A physicas professor presented the scatterplot above to her first-year students. What is the significance of the slope of the line of best fit ?

For the scatterplot above , which is closest to the slope of the line of best fit ?

Ten 25- year - old men were asked how many hours per week they exercise and their resting heart rate was taken in beats per minute (BPM). The results are shown as points in the scatterplot below, and the line of best fit is drawn. Which of the following is the best interpretation of the slope of the line of best fit in the context of this problem?

Ten 25 - years - old men were asked how many hours per week they exercise and their resting heart rate was taken in beats per minute (BPM). The results are shown as points in the scatterplot above, and the line of best fit is drawn. What is the resting heart rate, in BPM, of the men represented by the data point that is farthest from the line of best fit?

Michael swam 2,000 yards on each of eighteen days. The scatterplot above shows his swim time for and corresponding heart rate after each swim. The line of best fit for the data is also shown. For the swim that took 34 minutes, Michael’s actual heart rate was about how many beats per minute less than the rate predicted by the line of best fit?

Which of the following is most likely the slope of the line of best fit for the scatterplot above?

what is the greatest difference between the actual value of the stock and the value of the stock predicted by the line of best fit?
