Given information
The table of the data is given as,
Income | Ulcer rate (per 100 population) |
$4,000 | 14.1 |
$6,000 | 13.0 |
$8,000 | 13.4 |
$12,000 | 12.5 |
$16,000 | 12.0 |
$20,000 | 12.4 |
$30,000 | 10.5 |
$45,000 | 9.4 |
$60,000 | 8.2 |
Step-by-step explanation
Step 1.
From the table, consider the first and last data points are (4,000,14.1) and (60,000,8.2).
The slope of the linear equation is given by,
