<p>This is absolutely a place where you can ask simple questions.</p>

<p>However, it's important to understand how things work. In particular</p>

<ul>
<li><p>homework-style questions are treated specially (as noted there under your question), and usually require a clear indication of some level of effort on the part of the asker</p></li>
<li><p>good questions (see here in the <a href="https://stats.stackexchange.com/help/how-to-ask">help/how-to-ask</a>) should have made a clear effort at <em>search and research</em> (again, as noted there in comments under your question)</p></li>
</ul>

<p>Links were provided for both issues, so I thought what was required from you to get to a suitable question (in the form of edits you should make) would be pretty clear. With very simple (and very simply answered) questions it's even more important to follow the guidelines (otherwise you risk giving the impression you expect the site to do the equivalent of finding what page of your textbook the information is on).</p>

<p>Is there something at (the relevant parts of) those links that you think is ambiguous or not explained? We can perhaps clarify.</p>
