USA Today reported that 44.9% of those surveyed (1261 adults) ate in fast-food restaurants from one to three times each week. (Assume that the survey asked "Do you eat in fast-food restaurants from one to three times each week?")

The question is incomplete, the complete question is;

USA Today reported that 44.9% of those surveyed (1261 adults) ate in fast-food restaurants from one to three times each week. (Assume that the survey asked "Do you eat in fast-food restaurants from one to three times each week?") Identify the variable. Is the variable quantitative or qualitative? What is the implied population?

Answer:

a) Let the total population be x,

So here, 44.9% of x = 1261 and 44.9% = 44.9/100 = 0.499

thus, the variable here is the population (x),

and = > x = 1261 / 2527.05

b) it is quantitative.

c) Response from all adults is the implied population and response from 1261 adults surveyed is the sample.

Part A:

Given that USA Today reported that 44.9% of those surveyed (1261 adults) ate in fast-food restaurants from one to three times each week.

Given that the survey asked "Do you eat in fast-food restaurants from one to three times each week?"

The variable is the percentage of those who reported eating at fast food restaurants.

Part B.

Given that 44.9% of those surveyed ate in fast-food restaurants from one to three times each week.

The variable can be expressed as a quantitative data (a nubber) (i. e. 44%).

Thus, the variable is a quantitative variable.

Part C:

Given that USA Today reported that 44.9% of those surveyed (1261 adults) ate in fast-food restaurants from one to three times each week.

Since the people surveyed is a sample from adults, thus the implied population is all adults in the U. S.
