4.The Public debt increased at a relatively constant rate from 1986 to 1996. The following table gives the average debt per capita (in thousands of dollars) for selected years.
Let represent the average debt per capita (in thousands of dollars) and let the input t represent the number of years since 1986 (t=0). Use the linear regression features on your calculator to find an equation for f(t). Use your equation to answer the following questions
b. Find the t-intercept of your linear model. What does it mean in terms of the average debt per capita?
| Year (t) | d, average debt per capita in thousands of dollars |
| 1986 | 9 |
| 1988 | 11 |
| 1990 | 13 |
| 1992 | 16 |
| 1994 | 18 |
| 1996 | 20 |
Let represent the average debt per capita (in thousands of dollars) and let the input t represent the number of years since 1986 (t=0). Use the linear regression features on your calculator to find an equation for f(t). Use your equation to answer the following questions
- Find the d-intercept of your linear model. What does it mean in terms of the average debt per capita?
b. Find the t-intercept of your linear model. What does it mean in terms of the average debt per capita?
