On December 5, 2014, Clinical Pediatrics published the article “Fast Food Consumption and Academic Growth in Late Childhood.” The researchers found evidence that high levels of fast food consumption were associated with slower growth of academic skills in a study of 8544 fifth grade students. What is the population of interest?

One of the reasons that the Monitoring the Future (MTF) project was started was “to study changes in the beliefs, attitudes, and behavior of young people in the United States.”
Data are collected from 8th, 10th, and 12th graders each year.
To get a representative nationwide sample, surveys are given to a randomly selected group of students.
In Spring 2013, a study was done: 461 students were asked about alcohol, illegal drug, and cigarette use.

In their “Top Picks” feature in February 2014, Consumer Reports published an article on some new sport-utility vehicles they had tested recently.
They reported some basic information about each of the vehicles and the results of some tests conducted by their staff. Among other things, the article told the brand of each vehicle, its price, and whether it had a standard or automatic transmission.
They reported the vehicle’s fuel economy, its acceleration (number of seconds to go from zero to 60 mph), and its braking distance to stop from 60 mph.
The article also rated each vehicle’s reliability as much better than average, better than average, average, worse, or much worse than average.
Give a possible reason 'why' this research was performed (ex. what statistical question was being answered?)
Make sure your answer is clear for full credit. I will be grading this question myself.
