Suppose that a customer is purchasing a car. He conducts an experiment in which he puts 10 gallons of gas in the car and drives it until it runs out of gas. He conducts this experiment 15 times on each car and records the number of miles driven. Full data set Car 1 216 243 205 242 239 297 295 172 270 251 165 310 265 316 278 Car 2 231 220 223 205 245 257 242 292 248 252 287 255 250 293 251 Sample standard deviation for Car 1 s=________mi / 10 gal (Type an integer or decimal rounded to one decimal place as needed.) Sample standard deviation for Car 2 s=________mi / 10 gal (Type an integer or decimal rounded to one decimal place as needed.) Which car would the customer buy and why? Choose correct answer below. A. Car1, because it has a lower mean gas mileage. B. Car 2, because it has a lower sample standard deviation, hence more predictable gas mileage. C. Car1, because it has a larger range of gas mileage. D. There is very little difference between the two cars.

Sample standard deviation for Car 1
s=________mi / 10 gal
(Type an integer or decimal rounded to one decimal place as needed.)
Sample standard deviation for Car 2
s=________mi / 10 gal
(Type an integer or decimal rounded to one decimal place as needed.)
Which car would the customer buy and why? Choose correct answer below.
Car1, because it has a lower mean gas mileage.
Car 2, because it has a lower sample standard deviation, hence more predictable gas mileage.
There is very little difference between the two cars.
