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?
\[
\begin{array}{l}
H_{0}: p=0.7 \\
H_{1}: p> 0.7
\end{array}
\]
What type of test is being conducted in this problem?
Right-tailed test
Left-tailed test
Two-tailed test
What parameter is being tested?
Population standard deviation
Population proportion
Population mean
Answer
The parameter being tested is the \(\boxed{\text{Population proportion}}\).
Step 1 ：The null hypothesis (H0) is that the population proportion (p) is equal to 0.7.
Step 2 ：The alternative hypothesis (H1) is that the population proportion (p) is greater than 0.7.
Step 3 ：This suggests that we are conducting a right-tailed test because we are looking for an increase in the population proportion.
Step 4 ：The parameter being tested is the population proportion.
Step 5 ：The type of test being conducted in this problem is a \(\boxed{\text{Right-tailed test}}\).
Step 6 ：The parameter being tested is the \(\boxed{\text{Population proportion}}\).
