a.
Expert Solution
To determine
Identify the variable.
Answer to Problem 1.1HD
The variable is level of crankiness.
Explanation of Solution
Variable:
A variable is a characteristic or a condition of the subject under study, which can take several values.
The characteristic under study is the level of crankiness of the daughter, as decided by the father.
b.
Expert Solution
To determine
Identify the score.
Answer to Problem 1.1HD
The score is 2.
Explanation of Solution
The father provided a score of 2 on crankiness to his daughter. Thus, the score is 2.
c.
Expert Solution
To determine
Identify the range of the variable.
Answer to Problem 1.1HD
The range of the variable is 1 to 7.
Explanation of Solution
The crankiness score may take values between 1 and 7, on a 7-point scale. The minimum possible value on the scale is 1 and the maximum possible value is 7. Thus, the range of the variable is 1 to 7.

You are planning an experiment to determine the effect of the brand of gasoline and the weight of a car on gas mileage measured in miles per gallon. You will use a single test car, adding weights so that its total weight is 3000, 3500, or 4000 pounds. The car will drive on a test track at each weight using each of Amoco, Marathon, and Speedway gasoline. Which is the best way to organize the study?
Start with 3000 pounds and Amoco and run the car on the test track. Then do 3500 and 4000 pounds. Change to Marathon and go through the three weights in order. Then change to Speedway and do the three weights in order once more.
Start with 3000 pounds and Amoco and run the car on the test track. Then change to Marathon and then to Speedway without changing the weight. Then add weights to get 3500 pounds and go through the three gasolines in the same order.Then change to 4000 pounds and do the three gasolines in order again.
Choose a gasoline at random, and run the car with this gasoline at…
