a-1. Estimate the model Ownership = β₀ + β₁Income + ε. (Negative values should be indicated by a minus sign. Round your answers to 4 decimal places.) [If you are using R to obtain the output, then first enter the following command at the prompt: options(scipen=10). This will ensure that the output is not in scientific notation.]

yˆy^ = _______ + _______ Income

b. What is the standard error of the estimate? (Round your answer to 2 decimal places.)

Answer 1

The statistic software output for this problem is:

=  72.7089 - 0.0001 Income

b) Standard error = 5.53
