Answer to Problem 1.16E

This is an observational study.

Explanation of Solution

Given:

Child care In 2001, researchers announced that "children who spend most of their time in child care are three times as likely to exhibit behavioral problems in kindergarten as those who are cared for primarily by their mothers:"

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. This study involves the observation between two types of children, those who are in child care and those who are with their mother.

b)

To determine

To explain if we conclude from this study that child care causes behavior problems.

b)

Answer to Problem 1.16E

We can not conclude that child care causes behavior problems.

Explanation of Solution

Given:

Child care In 2001, researchers announced that "children who spend most of their time in child care are three times as likely to exhibit behavioral problems in kindergarten as those who are cared for primarily by their mothers:"

The behavior of child is depending on the parent’s actions towards their child. If parents aggressive then automatically child get aggressive. The child care having some time to spent for child. Hence, I don’t think child care causes behavior problems.
