Question

The predicted values were computed by using the line of best fit, y = 3.2x + 2.

A 4-column table with 4 rows. The first column is labeled x with entries 1, 2, 3, 4. The second column is labeled given with entries 16.1, 7.4, 11, 15. The third column is labeled predicted with entries 5.2, 8.4, 11.6, 14.8. The fourth column is labeled residual with entries a, b, c, d.

What are the residual values needed to complete the chart?

Answer 1

From the table we can say that the point which is residual plot of the data is (3,0).

What is residual plot?

Residual plot shows the difference between observed and fitted values of the data. It is also known as null residual plot. In this random values in data is taken.

How to find point?

We have been given the following table:

Age Value Predicted Residual

1 15 14.8 0.2

2 12 11.9 0.1

3 9 9 0

4 5 6.1 1.1

5 4 3.2 0.8

If we observe the table then we can find that the third row of fourth column contains 0 so the point which is residual plot of the data is (3,0).

Hence the point which contains the residual plot of the data is (3,0).

sorry nobody helped you

Answer 2

a = 0.9

b = -1

c = -0.6

d = 0.2
