Correct answer(s):
- T-statistic
The demand for video recorders has been estimated to be QV = 134 – 1.07PF + 46PM -2.1PV – 5I, where QV is the quantity of video recorders, PF denotes the price of video recorder film, PM is the price of attending a movie, PV is the price of video recorders, and I is income. Based on the estimated demand equation we can conclude:
Correct answer(s):
- Video recorders are inferior goods
