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
Answer
\( \boxed{\text{Population proportion}} \)
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 ：\( \boxed{\text{Population proportion}} \)
