# Basic T stat question

by DoubleTake   Last Updated October 10, 2019 06:19 AM

I missed this on a quiz and wanted to know if somone could explain it to me so i understand it for the final! thanks. I know its probably a really simple quesitons.

With a coefficient estimate of .8, 30 observations, and a t statistic of 4.00, whats the standard error?

Consider the general formula for a $$t$$-test:

$$t = \frac{\text{difference}}{\text{standard error}}$$

And the formula for the standard error of the mean:

$$\text{standard error} = \frac{\text{standard deviation}}{\sqrt{\text{sample size}}}$$

Can you work it out from there?
