a reporter for a local television station visits the citys new upscale shopping mall the day before christmas to interview shoppers. 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.\n\nselect 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.\n 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.\n having the reporter ask questions is not a double - blind study.\n surveying shoppers at the mall the day after christmas may not be a good representation of all shoppers in the city.\n surveying shoppers the day before christmas is a convenience sample, so it is a simple random sample.

Answer

# Brief Explanations: A simple random sample (SRS) requires every member of the population to have an equal chance of being selected. Shoppers at the mall the day before Christmas are a convenience - sample, not an SRS as not all city shoppers have an equal chance of being in the sample. A double - blind study is not relevant here as it pertains to experimental design, not sampling. Sampling the day after Christmas is not the issue with this particular sample. And convenience sampling is not the same as simple random sampling. # Answer: 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.
