For each of the following variables, identify the level of measurement (nominal, ordinal, interval, or ratio). (I) Fuel economy (miles per gallon) of a used car (II) Duration (in minutes) of a flight between two locationsa. (I) Ratio , and (II) Ratio
b. (I) Nominal , and (II) Ratio
c. (I) Nominal , and (II) Ordinal
d. (I) Interval , and (II) Nominal
e. (I) Ratio , and (II) Nominal

a).

(I) Ratio , and

(II) Ratio

Step-by-step explanation:

By fuel economy (miles per gallon) of a used car, it relates distance traveled by a vehicle and the amount of fuel consumed which can be expressed in terms of volume of fuel to travel a distance, or the distance traveled per unit volume of fuel consumed.

And by Duration (in minutes) of a flight between two locations, it has to do with time which is usually in Hour(s) (HH), Minutes (MM), Seconds (SS) or Mili-second(s) MS.

Hence, both variables are ratio. That is, the quantitative (continuous) observations. This is because, they can both take a decimal value and has true zero value. Consequently, the first option is correct!

NB: If the observation cannot take a decimal point or value, we say it is interval and has no true zero value.
