**Educational Transcription: Hypothesis Testing for Proportion Claims**

A humane society claims that less than 63% of households in a certain country own a pet. In a random sample of 500 households in that country, 300 say they own a pet. At \( \alpha = 0.10 \), is there enough evidence to support the society's claim? Complete parts (a) through (c) below.

**(a) Identify the claim and state \( H_0 \) and \( H_a \).**

Identify the claim in this scenario. Select the correct choice below and fill in the answer box to complete your choice. (Type an integer or a decimal. Do not round.)

- **A.** More than  ___ % of households in the country own a pet.
- **B.** ___ % of households in the country own a pet.
- **C.** Less than  ___ % of households in the country own a pet.
- **D.** The percentage of households in the country that own a pet is not ___ %.

Let \( p \) be the population proportion of successes, where a success is a household in the country that owns a pet. State \( H_0 \) and \( H_a \). Select the correct choice below and fill in the answer boxes to complete your choice. (Round to two decimal places as needed.)

- **A.** \( H_0 \): \( p \leq \) ___
- **B.** \( H_0 \): \( p \geq \) ___
- **C.** \( H_0 \): \( p < \) ___
- **D.** \( H_0 \): \( p > \) ___

**Explanation of Graphs or Diagrams:**

In this text, there is no explicit graph or diagram. The information pertains purely to setting up a hypothesis test based on given data. The essential steps here involve determining the claim and then specifying the null hypothesis (\( H_0 \)) and alternative hypothesis (\( H_a \)) related to the proportion of households owning pets. The choices A, B, C, and D offer potential ways to frame the hypotheses, and the appropriate values need to be filled based on the claim (less than 63%) and the sample data provided.

### Hypothesis Testing on Pet Ownership in Households

**Scenario:**

A humane society asserts that less than 63% of households in a specified country have a pet. In a random sample of 500 households within that country, 300 households reported owning a pet. Given a significance level of \( \alpha = 0.10 \), you are tasked with determining if there is enough evidence to support the society's claim. 

**Instructions:**

Complete parts (a) through (c) as outlined below:

**(a) Define the Hypotheses:**

Let \( p \) represent the population proportion of successes, where a success is defined as a household owning a pet. Establish the null hypothesis \( H_0 \) and alternative hypothesis \( H_a \). Select the appropriate hypothesis pair and fill in the corresponding values.

(Round to two decimal places as necessary.)

Options:

A.
\[ H_0: p \leq \_\_ \]
\[ H_a: p > \_\_ \]

B.
\[ H_0: p \geq \_\_ \]
\[ H_a: p < \_\_ \]

C.
\[ H_0: p < \_\_ \]
\[ H_a: p \geq \_\_ \]

D.
\[ H_0: p \neq \_\_ \]
\[ H_a: p = \_\_ \]

E.
\[ H_0: p > \_\_ \]
\[ H_a: p \leq \_\_ \]

F.
\[ H_0: p = \_\_ \]
\[ H_a: p \neq \_\_ \]

**(b) P-Value Calculation:**

Utilize statistical technology to compute the P-value for the test.

**(c) Standardized Test Statistic:**

Identify the standardized test statistic by calculating the z-score.

\[ z = \_\_ \]

(Round to two decimal places as needed.)

**Explanation of Hypotheses:**

When testing a hypothesis about a population proportion, we must set up our null and alternative hypotheses clearly:

- The null hypothesis (\( H_0 \)) usually represents the status quo or a statement of no effect or no difference.
- The alternative hypothesis (\( H_a \)) represents what we seek evidence for.

Given the scenario, we assert that less than 63% of households own a pet. Therefore, our hypotheses are framed around this
