Find the equation of the line of best fit and the correlation coefficient for the data shown. (1, 88), (2, 75), (3, 71), (4, 69), (5,66), (6, 68), (7, 50) Regression equation:
Explain your reasoning.
No, it is not reasonable to use the line of best fit to make predictions. The correlation coefficient r = 0.15 is close to 0, which indicates a very weak linear relationship between the variables. Therefore, the line does not fit the data well enough to provide reliable predictions.
There is a linear correlation between the data.
strong positive
As more years go by, the prediction (extrapolation) becomes ✔ lessequally more reliable.
The fuel efficiency of one type of car is recorded in a scatterplot where the amount of gas used, x (in gallons), is paired with the distance traveled, y (in miles), for various trips. The equation for the line of best fit for the data is y = 28x. How can the y-intercept and slope of this line be interpreted?
