4. Suppose that in the past years the average price per square foot for warehouses in Subic has been P32.28. A national real estate investor wants to determine whether that figure has changed now. The investor hires a researcher who randomly samples 19 warehouses that are for sale across Subic and finds that the mean price per square foot is P31.67, with a standard deviation of P1.29. If the researcher uses a 5% level of significance, what statistical conclusion can be reached?
