Question 1 2 pts The band director at a high school wants to know what percentage of parents supports a decrease in the budget for fine arts. Because many parents attend the school's annual musical, the director surveys the first 30 parents who arrive at the show. This sampling method (convenience sampling) is biased because it is likely that the first 30 parents to arrive at the show are very strong supporters of the fine arts. As a result, the proportion of parents in the sample who support the decrease in the budget will be less than the proportion of parents in the population who support the decrease. Explain how to avoid the bias described in the problem. Instead of sampling the first 30 parents who arrive at the school's annual musical, the band director could obtain a list of all the high school parents and [ Select ] from this list to be surveyed. If [ Select ] is used instead of convenience sampling, no personal choice is involved and the sample should be [ Select ] representative of all high school parents.

To vote on the name, people simply needed to visit a website and record their choice. Ignoring names suggested by the council, more than 124,000 people voted for "Boaty McBoatface," which ended up having more than 3 times as many votes as the second-place finisher. Explain why this sampling method is biased. O This sampling method (convenience sampling) is biased because it is likely that people who took the time to go online and vote did so to amuse themselves by voting for a silly name. This sampling method (voluntary response sampling) is biased because it is likely that people who took the time to go online and vote did so to amuse themselves by voting for a silly name. The sampling method (voluntary response sampling) is biased because this is an observational study. The sampling method (convenience sampling) is biased because this is an observational study. D Question 5 2 pts Many websites include customer reviews of products, restaurants, hotels, and so on. The manager of a hotel was upset to see that 26% of reviewers on a travel website gave the hotel a "1 star" rating-the lowest possible rating. Explain why this sampling method is biased.
