a)
To give the list of the question of interest.
a)
Explanation of Solution
Given:
According to the National Institute on Media and the Family, a preschooler’s risk of obesity jumps 6% for every hour of television watched per day. The risk increases by 31% if the TV is in their bedroom.
The study is about the watching a risk of watching a TV and relative risk of watching a TV in their bedroom. Therefore, the question arises are:
1)How much do you watch a television per day?
2)Do you have a TV in your bedroom?
b)
To identify whether the observational study or experimental study.
b)
Answer to Problem 1.32E
This is an observational study.
Explanation of Solution
Given:
According to the National Institute on Media and the Family, a preschooler’s risk of obesity jumps 6% for every hour of television watched per day. The risk increases by 31% if the TV is in their bedroom.
First need to understand about the experimental study and observational study:
Experimental study: Assigning people or things to groups and applying some treatment to one group, while the other group does not receive the treatment.
Observation study: In an observational study, measure or survey members of a sample without trying to affect them.
This study is an observation study. In this study, the researcher asked to people about the watching a television.
c)
To individuals and variables.
c)
Explanation of Solution
Given:
According to the National Institute on Media and the Family, a preschooler’s risk of obesity jumps 6% for every hour of television watched per day. The risk increases by 31% if the TV is in their bedroom.
First need knows about the individual and variables:
The individuals are said to be an object of a data described by the set of data.
The variables are the headers in which survey is investigated.
The individuals are preschooler’s which having ages 1 to 4. The variables are Number of hours of watching a TV and TV in bedroom.
