This is a quick hybrid-pi analysis of a common-emitter amplifier, values as given except early voltage = 200V and thermal voltage = 25mV@300k.
Re = Vt / IC = 25mV / 1mA = 25 Ohm
gm = 1 / (Re + RE) = 1 / (25 + 3000) = 330uS
RIn = hfe / gm = 100 / 330uS = 303kOhm
Rout = VA / IC = 200V / 1mA = 200kOhm
Av = -gm * RC = -330uS * 5000 = -1.65
Zin (bias network) = ~40kOhm
