<p>In my view my questions must be super easy and I make obvious mistakes as I am naive and learning on my own as I tackle real life problems. Nonetheless my questions remain unanswered. Any idea what's the cause? I feel that something must be wrong with me.</p>

<p>Here are the unanswered questions of mine in Cross Validated:</p>

<ul>
<li><a href="https://stats.stackexchange.com/questions/211447/how-to-calculate-the-confidence-interval-of-the-mean-of-means-2">How to calculate the confidence interval of the mean of means? (2)</a></li>

</ul>

<p>One of which I deleted in Cross Validated, and pasted it in Mathematics as I hypothesized that may it's due to me posting in wrong community:</p>

<ul>

</ul>

<p>Side note: not sure if related to the problem at hand, but one mistake I did is that I abused the "self-study" tag. What I really meant was some kind of self-learning where I try to tackle real life problems by having me learn individually. I think this is not what "self-study" is for.</p>
