Question: Fred Holtz Marketing Consultants has a problem. Their biggest customer, Fiat of America, plans on introducing there 100% electric coupe into the United States market to be distributed under the Chrysler brand. Holtz Marketing will be handling the marketing surrounding battery maintenance. The problem is that the batteries cost $16,000 and have to be replaced every 3 years. That $16,000 is half of the $32,000 price-tag. It is the job of Holtz to offer some benefits to downplay the sting of the battery maintenance cost. Holtz is proposing to offer either lifetime maintenance on the car for everything but the battery or a professionally installed home quick charger, which can give the car a full charge in under an hour. To pick the best alternative, Holtz runs a market research study in 20 different regions. In 10 regions the lifetime maintenance will be offered and the other 10 will be offered the home charger. The dependent variable is the number of people who said they would buy the car if offered that perq. Numbers are in hundreds
