We are interested in the population proportion of drivers who claim they always buckle up. Use this scenario for the next 4 questions. What is the meaning of p ^ in the context of this scenario? Group of answer choices the proportion of drivers who claim they always buckle up in the POPULATION Neither of these the proportion of drivers who claim they always buckle up in the SAMPLE What is the value of p ^ in the context of this scenario? f you wanted to estimate the true percentage of drivers who claim they always buckle up to within 1% error with 95% confidence, how many drivers would you need to survey? You may use the pilot study as a preliminary estimate of p ^.
