5) Suppose we are conducting a Presidential approval poll of 1,500 likely voters. Suppose that we already know that 36% of likely voters in the United States are registered Democrats, 38% are registered Republicans, and 26% are Independents. If we are going to construct a representative sample of this population, how many of the likely voters in the sample should be:

PartA: Registered Democrats?

PartB: Registered Republicans?

PartC: Independents?
