SCENARIO #2: You are a market research analyst at Colgate Palmolive. You have been asked to do a survey among adult Canadians to better understand oral hygiene habits, including perceptions and usage of Colgate products versus other brands. You have been asked to do this research among a representative sample of Canadian adults.

2a) Use your own words to explain the advantages of sampling research and explain why you have decided to survey only 1500 Canadians. (3 points)

2b)Assuming the expected response rate is 35%, how many samples do you need to obtain 1500 completed surveys? (1 point)

2c) What regional quotas would you set for a nationally representative sample? Provide a chart showing the % and counts of the 1500 interviews that should come from Western Canada, Ontario, Quebec, and Atlantic Canada. (8 points)

2d)Do you think this research should be limited only to customers of Colgate Palmolive products? Why or why not? (3 points)
