#### Task (a): Compute the Residuals
The residuals need to be computed for the matrix provided below. 

| Years of Experience | Annual Sales (\$1,000s) | Residuals            |
|---------------------|-------------------------|----------------------|
| 1                   | 80                      | [Input Field]        |
| 3                   | 97                      | [Input Field]        |
| 4                   | 97                      | [Input Field]        |

| 6                   | 103                     | [Input Field]        |
| 8                   | 101                     | [Input Field]        |
| 10                  | 119                     | [Input Field]        |
| 10                  | 123                     | [Input Field]        |
| 11                  | 127                     | [Input Field]        |
| 13                  | 136                     | [Input Field]        |

### Explanation of Diagrams and Graphs
In this exercise, we are provided with two tables. The first table details the sales data of 10 different salespeople, including their years of experience and their annual sales measured in thousands of dollars. The second table requires the user to compute the residuals for a given set of data involving years of experience and annual sales. Residuals are the differences between the observed values and the estimated values. Each input field provided in the second table will allow users to compute these residuals based on a regression or another fitting method applied to the data.
