You regress Y on x and Z and get the following set of results (which I've adjusted to be nice and round so the calculations in this problem are easy. No significance stars areshown):
feols(y x + z..
Dependent var : y
Constant 0.0100(0.0100)
x 1.500 (0.5000)
z 3.000 (2.000)
S.E. type IID
Observation 10,000
R2 0,900000
Calculate te t statistic that test whether the coefficient on z is equal to 5
