renault wanted to get opinions from $500$ auto retailers on their new car. The list of retailers is divided into $100$ large and $400$ small retailers. $$ahin bey the marketing manager drew a random sample of $50$ retailers and was dissapointed to find only $4$ large retailers in the sample,since large retailers represent more than $30$ percent of the potential sales. Kartal,his friend, suggests drawing another sample $($with the same process$).$ What do you recommend? What other pieces of information would you like to have?
