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. Describe each data set, that is determine the shape, center, and spread. Sample mean for Car 1 mi / 10 gal X= Full data set D (Type an integer or decimal rounded to one decimal place as needed.) Car 1 234 242 235

Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.

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.
Describe each data set, that is determine the shape, center, and spread.

(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.)
Which car would the customer buy and why?
O A. Car 2, because it has a lower sample standard deviation, hence more predictable gas
mileage.
O B. Car 1, because it has a larger range of gas mileage.
O C. Car 1, because it has a lower mean gas mileage.
