Question
A null and alternative hypothesis is given. Determine whether the hypothesis test is left-tailed, right-tailed, or two tailed. What parameter is being tested?$$\begin{aligned}&H_{0}: p=0.2\\&H_{1}: p<0.2\end{aligned}$$
Step 1
To do this, we need to understand the definitions of each type of test. A right-tailed test is when the parameter is greater than a certain value in the alternative hypothesis ($H_{1}$). A left-tailed test is when the parameter is less than a certain value in Show more…
