To determine whether voters would be willing to vote for a tax increase to improve the city's parks, the park commission surveys 500 park users. why is this sample likely to be biased? a. park users are more likely to be willing to pay more to improve parks. b. park users are too busy to be bothered with surveys. c. there are not enough people in the sample. d. the entire population of the city was not surveyed.

 The answer is A

Step-by-step explanation: Think about the question and what it is asking about, raising taxes to improve the city's parks, now think about who benefits from the parks. Park users right? Okay, but since tax increase will be put on everyone living in the city, some do not use the park. Is it fair to base the survey question just to park users? No, it's biased to base it on park users only. Of course the park users will be okay improving the parks they use. An unbiased survey would ask a sample of citizens in the city whether it's a good idea to raise taxes to improve the city parks. It's not just the park user whose taxes will be raised for the improvements.
