A t-test of the difference between the pre- and the post-intervention data means could be done to ascertain the difference. A more holistic approach is to fit an ARIMA model to the pre-intervention data as recommended by Box and Tiao (1975) who pioneered this approach. Then generate post-intervention forecasts on the basis of the model.
