Becky surveyed the 32 shoppers who spent the most time and money at her boutique last month.  Will this result in a representative sample? Why or why not?

• Yes, because everyone that enters the shop had an equal chance of being surveyed.

• Yes, because all 32 shoppers who spent the most time and money there were surveyed.

• No, because she did not survey any shoppers who spent small amounts in her shop.

• No, because she needed to step outside and only survey people who walked by her boutique.
