Question

4. Use the given data to find the equation of the regression line. Examine the scatterplot and identify a characteristic of the data that is ignored by the regression line.

x              y

12           8.86

13           8.11

7              8.45

10           9.54

8              9.10

9              9.45

6              7.54

11           9.34

4              4.86

3              3.11

5              6.34

Ŷ=____+____x

(Round to two decimal places as​ needed.)

Create a scatterplot of the data.

Identify a characteristic of the data that is ignored by the regression line.

A.There is no trend in the data.

B.The data has a pattern that is not a staight line.

C.There is an influential point that strongly affects the graph of the regression line.

D.There is no characteristic of the data that is ignored by the regression line.

Answer 1

The statistical software output for this problem is:

Hence,

Regression equation will be:

Ŷ = 3.7 + 0.5 x

Characteristic: Option B is correct.
