The data set entitled ‘Salmon’ contains 40 annual counts of the
numbers of recruits
and spawners in a salmon population. The units are thousands of
fish. Recruits are fish that
enter the catchable population. Spawners are fish that are laying
eggs. Spawners die after
laying eggs.
The classic Beaverton-Holt model for the relationship between
spawners and recruits is
R = 1 /(β1 + β2/S)
where R and S are the numbers of recruits and spawners,
respectively. This model may be...

Researchers in a 2015 study by Flannery et al. sought to

Use the Manufacturing database from “Excel Databases.xls” on
Blackboard. Use Excel to develop a multiple regression model to
predict Cost of Materials by Number of Employees, New Capital
Expenditures, Value Added by Manufacture, and End-of-Year
Inventories.
Locate the observed value that is in Industrial Group 12 and has
7 employees. Based on the model and the multiple regression output,
what is the corresponding residual of this observation? Write your
answer as a number, round to 2 decimal places.
