please you explain the data set use here

In a study of three nationally representative large-scale data sets from Ireland, the United States, and the United Kingdom (n = 17,247), teenagers between the ages of 12 to 15 were asked to keep a diary of their screen time and answer questions about how they felt or acted.

The answers to these questions were then used to compute a psychological well-being score. Additional data were collected and included in the analysis, such as each child's sex and age, and on the mother's education, ethnicity, psychological distress, and employment.

The study concluded that there is little clear-cut evidence that screen time decreases adolescent well-being.

Identify the response variable.
Can the results of the study be generalized to the population of Irish, USA, and UK teenagers? Why or why not?
Can the results of the study can be used to determine if screen time affects adolescent well-being? Why or why not?
