CI for $\mu$:

$H_0:\mu$
$H_a:\mu$

Significance level: $\alpha =$

This applet computes performs inference for a population mean $\mu$.

Assume

$X_i \stackrel{iid}{\sim} N(\mu,\sigma^2)$ for $i=1,\ldots,n$

Directions

To perform a hypothesis test for $\mu$, enter $H_0$ and $H_a$. Specify the null and alternative hypotheses with the drop-down boxes. The critical value, rejection region, test statistic, and $p-$value are computed and graphed. Different significance levels can be chosen with the drop-down box.
