Please advise: t-test for OLS dummy variable

#1
Hi.
I need help. I'm writing a proposal and am not a statistician and am having trouble translating the notes from my professor into an equation.
He said, after running my OLS twice, I will "test whether the estimated coefficient (beta) on the dummy variable for CCMI is statistically significant.
You will do this by dividing the estimated beta on the CCMI dummy variable by its associated standard error and perform a t-test"

Is this correct?

t = (β CCMI)/(s.e.)

greatly appreciated...
