Draw a scatterplot

Question

For the following table of​ data,

a. Draw a scatterplot.

b. Calculate the correlation coefficient.

c. Calculate the least squares line and graph it on the scatterplot.

d. Predict the​ y-value when x is 11

x y

1 0.1

2 0.7

3 1.1

4 2.1

5 2.9

6 3.1

7 3.1

8 4.4

9 4.6

10 5.1

Answer 1

1) plot your points accordingly into a x-y axis

2) r = .987611

3) graph the line y^{^}=.557576x-.346667

4) plug 11 into equation in part 3). the predicted y-value is 5.786669

The linear regression equation and r can be found under a linear regression function in the ti-84. You must list your data into two lists first.
