Step 1 :The standard quota for a state is calculated by multiplying the total number of seats by the ratio of the state's population to the total population. In this case, the total number of seats is 441 and the total population is 310 million. The population of state C is 11,995,000.
Step 2 :Calculate the standard quota for state C using the formula: \(\frac{{\text{{State C Population}}}}{{\text{{Total Population}}}} \times \text{{Total Seats}}\). Substituting the given values, we get \(\frac{{11995000}}{{310000000}} \times 441\), which equals approximately 17.06.
Step 3 :Compare the standard quota with the number of representatives state C has. State C has 18 representatives.
Step 4 :If the standard quota is less than the number of representatives, then state C is overrepresented. If the standard quota is more than the number of representatives, then state C is underrepresented.
Step 5 :The standard quota for state C is approximately 17.06, which is less than its number of representatives, 18. Therefore, state C is overrepresented.
Step 6 :Final Answer: \(\boxed{17.06}\). State C is overrepresented because its standard quota of 17.06 is less than its number of representatives, 18.
