the conditional relative frequency table was generated using data that compares the number of voters in the last election and whether or not they worked on election day. fifty people who voted and 85 people who did not vote were chosen at random and surveyed. how many people in the survey worked on election day? 32 34 66 69 did vote did not vote total did work 0.64 0.41 0.49 did not work 0.36 0.6 0.51 total 1.0 1.0 1.0
Answer
Explanation:
Step1: Calculate number of voters who worked
The number of people who voted is 50, and the conditional relative - frequency of voters who worked is 0.64. So the number of voters who worked is $50\times0.64 = 32$.
Step2: Calculate number of non - voters who worked
The number of people who did not vote is 85, and the conditional relative - frequency of non - voters who worked is 0.4. So the number of non - voters who worked is $85\times0.4=34$.
Step3: Calculate total number of people who worked
Add the number of voters who worked and non - voters who worked. $32 + 34=66$.
Answer:
66
