1. The problem asks: How many people in the survey worked on election day? 2. We are given a conditional relative frequency table with the following data: - Total people who voted: 50 - Total people who did not vote: 85 - Relative frequencies for "Did Work" row: 0.64 (Did Vote), 0.4 (Did Not Vote), total 0.49 - Relative frequencies for "Did Not Work" row: 0.36 (Did Vote), 0.6 (Did Not Vote), total 0.51 3. The total number of people surveyed is $50 + 85 = 135$. 4. The total proportion of people who worked on election day is 0.49 (from the "Total" column for "Did Work"). 5. To find the number of people who worked, multiply the total number surveyed by the proportion who worked: $$ \text{Number who worked} = 135 \times 0.49 $$ 6. Calculate: $$ 135 \times 0.49 = 66.15 $$ 7. Since the number of people must be a whole number, we round to the nearest whole number: $$ 66 $$ 8. Therefore, the number of people in the survey who worked on election day is 66.
