In a certain year, the average annual family income in the National Capital Region was P310,860 with a standard deviation of P176,870. With the increased prices of commodities, it is hoped that the mean annual family income has also increased. A survey is conducted to verify this claim. A random sample of 320 families has a mean annual income of P325,255. Which is the most appropriate null hypothesis to choose? " H, : µ = P310, 860 H, : µ 2 P310, 860 Option 1 Option 2 Ha : µ > P310, 860 H, : µ < P310, 860 Option 3 Option 4
