A sports analyst claimed that worldwide, soccer is the most popular sport. An independent study selects a random sample of 500 adults from around the globe and asks each person, "What is your favorite sport?". They find that 246 of the respondents prefer soccer. Then, they compute a 90% confidence interval for the true proportion of all adults that prefer soccer as their favorite sport. Which of the following steps, if any, contain an error? Plan: One-sample z interval for p. Random? Random sample of 500 adults. Yes! Large Counts? 246 ≥ 10and254 > 10. Yes! None of the steps contain an error. Conclude: We are 90% confident that the interval from 0.455 to 0.529 captures the proportion of all Adults who prefer soccer as their favorite sport. State: We want to estimate p = the proportion of all adults who prefer soccer as their favorite sport at a 90% confidence level. Do: (0.455, 0.529)
