Ans<em>wer:</em>
<em>Kira used published data that is quantitative.</em>
<em>Step-by-step explanation:</em>
<em>Firstly, we need to identify if the data is qualitative or quantitative.
</em>
<em>The data is average number of people living in the homes.
</em>
<em>
</em>
<em>Qualitative data as its name indicates is an attribute or characteristic. It can not be measured e.g color. Quantitative data is such a data which can be counted or measured.

<em>Since the average number of people can be counted and measured, the data is Quantitative.
</em>
<em>In an observational study the individuals are observed. In the given case, Kira did not observed the individuals to gather the data, rather she used an Online resource to gather the data.
</em>
<em>
</em>
<em>Therefore, the correct answer will be:
</em>
<em>Kira used published data that is quantitative.</em>
