The local Girl Scout troupe wants to know how to price the raffle tickets for their up-coming fund drive. To find out what people are willing to pay for a ticket to win a romantic weekend in Gatlinburg, they use a survey and solicit customers entering a local Kroger’s grocery to take the survey. Survey takers are asked if they would buy a $10 ticket with the following possible responses: maybe, never, probably, and certainly. 

• Determine whether this study corresponds to an observational study or an experiment. 

• Are these responses qualitative or quantitative? 

• Determine which of the four levels of measurement is most appropriate for these responses. 

• Identify the population of this study. 

• Identify the sample of this study. 

• Identify the sampling methods. 

• Is this sample likely to be representative of the population? Explain your answer
