Describe each data set, that is determine the shape, center, and spread.
Sample mean for Car 1
X=
mi / 10 gal
(Type an integer or decimal rounded to one decimal place as needed.)
Sample mean for Car 2
X =
mi / 10 gal
(Type an integer or decimal rounded to one decimal place as needed.)
Median for Car 1
M =
mi / 10 gal
(Type an integer or decimal rounded to one decimal place as needed.)
Median for Car 2
M =
mi / 10 gal
(Type an integer or decimal rounded to one decimal place as needed.)
Range for Car 1
R= mi / 10 gal
(Type an integer or decimal rounded to one decimal place as needed.)
Range for Car 2
R=
mi / 10 gal
(Type an integer or decimal rounded to one decimal place as needed.)
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.)
Transcribed Image Text:A. Car 1, because it has a lower mean gas mileage.
B. Car 2, because it has a larger range of gas mileage.
C. Car 1, because it has a lower sample standard deviation, hence more predictable
