Imagine everyone in the United States exhibited the character traits we have been discussing. In what ways would America be different? Now imagine no one in American exhibited any of those character traits. In what ways would America be different?

The frequencies refer to the sample data collected from a population of interest when performing a hypothesis test comparing two or more population proportions.

Ahair dryer is basically a duct in which a few layers of electric resistors are placed. a small fan pulls the air in and forces it through the resistors where it is heated. air enters a 1200 w hair dryer at 100 kpa and 22°c and leaves at 47°c. the cross-sectional area of the hair dryer at the exit is 60 cm2. neglecting the power consumed by the fan and the heat losses through the walls of the hair dryer, determine (a) the volume flow rate of air at the inlet and (b) the velocity of the air at the exit.
