Here is a slightly less toylike example:

webuse grunfeld, clear
scalar tavg = 0
scalar navg = 0
forv i=1/10 {
	reg invest mvalue if company == `i'
	scalar tavg = tavg + e(N) * abs(_b[mvalue] / _se[mvalue])
	di `i' " " tavg
	scalar navg = navg + e(N)
}
scalar tavg = tavg / navg
scalar navg = navg / 10
scalar pavg = ttail(navg, abs(tavg))
di _n "Average t(" navg ") = " tavg " with pval = " pavg
