In California in 2000, the ballot included an initiative to add "none of the above" to the list of options in all candidate race
s. Prior to the election, a Field Poll indicated that support for the measure was 10% below opposition for the measure. The poll was a telephone survey of 1000 registered voters in California. According to the Field Poll, "The survey was completed by telephone in English and Spanish using random digit dialing methods." A spokesperson for the initiative was critical of the poll because only 1000 people were surveyed. He pointed out that there are 23.5 million registered voters in California. Is his criticism valid? Group of answer choices No, because the sample was randomly selected. Yes, because it is impossible for 1,000 people to be representative of 23,500,000 people. No, because he was a spokesperson for the initiative, so he is biased. Yes, because a telephone survey will not represent the opinions of those without telephones.
In this example, the main element that we need to focus on is the way in which the sample was determined. We learn that the sample was taken in California with 1000 people. However, this sample was random, and the survey was conducted in both English and Spanish. The fact that this was a random sample means that it is representative of the population. The size of the population does not affect the accuracy of a random sample.
Resort A has more consistent snowfall, so it shows less variation. However, the snowfall for Resort B has a higher median, and the interquartile range is higher (not larger), so it is more likely that Kevin will find a good snowfall at Resort B.
