The null and alternative hypotheses are given. Determine whether the hypothesis test is left-tailed, right-tailed, or two-tailed. What parameter is being tested? \[ \begin{array}{l} H_{0}: p=0.8 \\ H_{1}: p \neq 0.8 \end{array} \] Two-tailed test Left-tailed test Right-tailed test What parameter is being tested? Population standard deviation Population mean Population proportion Time Remaining: 00:58:17

Step 1 ：Determine the type of hypothesis test based on the alternative hypothesis \(H_{1}\).

Step 2 ：Identify the parameter being tested based on the null hypothesis \(H_{0}\).

Step 3 ：Since the alternative hypothesis \(H_{1}\) has a 'not equal to' sign (\(\neq\)), it indicates a two-tailed test.

Step 4 ：The parameter being tested, represented by the symbol \(p\) in the null hypothesis \(H_{0}\), is the population proportion.

Step 5 ：\( \boxed{\text{Two-tailed test}} \)

Step 6 ：\( \boxed{\text{Population proportion}} \)
