Question

Suppose that you were also given the following output from the model summary: 

Residual standard error: 3.882 on 28 degrees of freedom
Multiple R-squared:  0.948,Adjusted R-squared:  0.9442
F-statistic:   255 on 2 and 28 DF,  p-value: < 2.2e-16

Which of the following is the correct equation for constructing a 95% confidence interval for the slope of cabinets?

0.3393 ± ( z∗ )(0.0145) 

0.3393 ± ( t∗28 )(0.1302) 

0.3393 ± ( t∗2 )(0.1302) 

0.3393 ± ( z∗ )(2.607)
