# Math Help - Standard Error of b1

1. ## Standard Error of b1

I'm given a bunch of data and told to find b0, b1, the standard error of b1, and the least-squares regression equation.

I calculated b0 and b1, but how do I find the standard error of b1?

I'm given n, the sample mean, and the sample variance for both variables.

Any help appreciated!

2. First you obtain the variance and it's a lot easier using matrices.
