QuestionAt least 68%68 \% of phone numbers in a certain city are unlisted. Express the null and alternative hypotheses in symbolic form for this claim (enter as a percentage). H0:pH_{0}: p \square H1:pH_{1}: p \square Use the following codes to enter the following symbols:  enter >=  enter <=  ‡ enter != \begin{array}{l} \geq \text { enter >= } \\ \vdots \text { enter <= } \\ \text { ‡ enter != } \end{array}

Studdy Solution
The alternative hypothesis (H1H_1) represents the claim that the proportion of unlisted phone numbers is less than 68%68\%. This is expressed as:
H1:p<68% H_1: p < 68\%
The symbolic form of the hypotheses is:
H0:p68% H_0: p \geq 68\% H1:p<68% H_1: p < 68\%
