a) true
b) false

A researcher designs a study to see if height and weight are related, so it is false that they would use an experimental design to carry out this study.

Since in the given question, we need to find out the relation between height and weight. So, Correlational research is needed. For the case, the variables of height and weight are regularly related (correlated) because taller people usually weigh more than smaller people.

Correlational research is research intended to identify correlations among variables and to allow the foresight of future events from present information. Correlational research designed is used to assess the relationships between and among two or more variables. When there are two variables in the research design, one of them is named the predictor variable and the other the outcome variable.
