- A survey indicates that you should always try to negotiate for a better deal when shopping or paying for services. In fact, based on this survey, 30% of the people under the age of 34 were more likely to "haggle," compared to only 10% of those aged 65 and older. Suppose that this survey included 90 people under the age of 34 and 60 people who are 65 or older.

In 2013, the Gallup pollasked 1,039 American adults if they believe there was a conspiracy in theassassination, and found that 634 believe there was a conspiracy ("Gallup newsservice," 2013).

He questions the first 25 shoppers he meets outside one of department stores at the mall. He asks them whether their overall feelings about Christmas shopping are positive, neutral, or negative. Select the reason(s) why it may be risky to act as if the first 25 shoppers at this particular location are an SRS of all shoppers in the city. Surveying shoppers the day before Christmas is a convenience sample, so it is a simple random sample. Shoppers at the mall the day before Christmas does not guarantee every shopper in the population has an equal chance to be in the sample. Surveying shoppers at the mall the day after Christmas may not be a good represenation of all shoppers in the city. Having the reporter ask questions is not a double‑blind study.arrow_forward
