d_{n+1}=d_n\,+\,2^n

with d_1=81

Step-by-step explanation:

We can study what happens day by day starting with day one (1) to understand how the recursive relation can be constructed:

Day #     Number of stamps     What is added relative to previous day

1               d1 = 80 + 1 = 81

2              d2 = 81 + 2 = 83            d2 = d1 + 2

3              d3 = 83 + 4 = 87           d3 = d2 + 2^2

4              d4 = 87 + 8 = 95           d4 = d3 + 2^3

5              d5 = 95 + 16 = 111          d5 = d4 + 2^4

6              d6 = 111 + 32 = 143        d6 = d5 + 2^2

(n+1)                                               d(n+1) = dn + 2^n

(A) Population data

(B) The figures

(C) The classification of votes by political party

Step-by-step explanation:

(A) These results summarize population data. The population is the total 3,889 voters from whom information was collected.

The samples would be

- Voters registered as Democrats  (1,633)

- Voters registered as Republicans  (1,206)

- Independent Voters  (1,050)

The total of members in each sample equals the total number of people in the population.

(B) A descriptive aspect of the result is the figures or percentages. They describe how (in percentage) voters penned their votes for Brown and how they penned their votes for Whitman. NOTE: To get the percentage or fraction of those who voted for Whitman, simply subtract the percentage of Brown's supporters from a total of 100%.

(C) An inferential aspect of the results is the classification of votes by different parties (the samples are the different parties involved here). This helps to infer the sources of support for Brown and the sources of support for Whitman.

For example, if the total votes for Brown (in population result analysis) are low, the Republicans are the major reason why!
