Use the given data to find the quation of the regression lin

Use the given data to find the quation of the regression line. Examine the scatterplot and identify a characteristic of the data that is ignored by the regression line 12 4 13 10 5.36 8.36 6.92 1.92 7.79 8.22 6.61 8.61 7.57 8.57 3.79 y = + Lx (Round to two decimal places as needed.) Create a scatterplot of the data. Choose the correct graph below OA. ^-D + x (Round to two decimal places as needed ) OC. 0 5 10 15 20 25 0 5 10 15 20 25 0 5 10 15 20 25 0 5 10 15 20 25

Solution

Using technology to find the regression equation,

y = 2.20 + 0.50x

***************************

Plotting the data, you can see that it is a downward parabola, OPTION D. [ANSWER]

********************************

As you can see, THE DATA HAS A PATTERN THAT IS NOT A STRAIGHT LINE. [ANSWER, OPTION A]
