Question
The decline of salmon fisheries along the Columbia River in Oregon has caused great concern among commercial and recreational fishermen. The paper 'Feeding of Predaceous Fishes on Out-Migrating Juvenile Salmonids in John Day Reservoir, Columbia River' (Trans. Amer. Fisheries Soc. (1991: 405-420) gave the accompanying data on y = maximum size of salmonids consumed by a northern squaw fish (the most abundant salmonid predator) and x = squawfish length, both in mm. Here is the computer software printout of the summary:
| Coefficients: | ||||
| Estimate | Std. Error | t value | Pr(> |t|) | |
| (Intercept) | −89.010 | 16.720 | −5.324 | 0.000 |
| Length | 0.704 | 0.049 | 14.333 | 0.000 |
Using this information, give the equation of the least squares regression line.
