(a) Globally, registrations of new electric cars have increased in recent years, despite the pandemic, as motorists start to embrace all-electric vehicles to reduce CO2 emissions. However, many motorists have concerns such as price, a lack of availability of public charging points, and driving range limitations on a single battery charge. You work in the marketing department of a global car manufacturer that is in the carly stages of developing their electric vehicle range of models. The company wants to better understand drivers' opinions about electric cars and their intention to purchase an electric car when they next trade in their vehicle. The company suspects that sentiment may vary from country to country, as well as by gender and age. The company has a database of customers who have previously bought at least one of their non-electric vehicles which includes their contact details and main demographic attributes. To better understand where to target their research and development (R&D) budget, the company's management has decided to use a survey of all types of customers and has asked you to devise an appropriate sampling scheme. Explain in detail how each of the following sampling methods could be applied to the overall sampling strategy for this study. Make sure you describe the merits and limitations of each as well as how cach would be applied in practice. i. Quota sampling. ii. Snowball sampling. iii. Simple random sampling. iv. Cluster sampling
