Historically, the percentage of residents of a certain country who support stricter gun control laws has been 53%. A recent poll of 987 people showed 500 in favor of stricter gun control laws. Assume the poll was given to a random sample of people. Test the claim that the proportion of those favoring stricter gun control has changed. Perform a hypothesis test, using a significance level of 0.05. State the null and alternative hypotheses. Họ: The population proportion that supports stricter gun control is 0.53, p= 500 H p #0.53 (Type integers or decimals. Do not round.) The significance level is a = 0.05. Choose the one-proportion z-test. Compute the sample proportion p. (Round to four decimal places as needed.) Calculate the values needed to compute the standard error.

Transcribed Image Text:Historically, the percentage of residents of a certain country who support stricter gun control laws has been 53%. A recent poll of 987 people showed 500 in favor of stricter gun control laws. Assume the poll was given to a random sample of people. Test the claim that the proportion of those favoring stricter gun control has changed. Perform a hypothesis test, using a significance level of 0.05.
1. **State the null and alternative hypotheses:**
- \( H_0 \): The population proportion that supports stricter gun control is 0.53.
- \( H_a \): \( p \) (symbol for the population proportion being considered) is not equal to 0.53.
2. **The significance level is \(\alpha = 0.05\). Choose the one-proportion z-test.**
3. **Compute the sample proportion \(\hat{p}\):**
- \(\hat{p} = \frac{500}{987}\)
4. **Calculate the values needed to compute the standard error.**
(Note: Detailed calculations would involve computing the exact sample proportion and further statistical values, such as standard error, z-score, and p-value, to conclude the hypothesis test.)
![### Hypothesis Testing: Z-Test Example
Historically, the percentage of residents of a certain county who support stricter gun control laws has been 53%. A recent poll of 9897 people found that 5293 support stricter gun control. Test the claim that the proportion of those favoring stricter gun control has changed. Perform a hypothesis test using the following steps.
#### Identify the values needed to compute the z-test statistic.
**Z Formula:**
\[ Z = \frac{\hat{p} - p}{SE} \]
Where:
- \(\hat{p}\) = Sample proportion
- \(p\) = Population proportion
- \(SE\) = Standard Error
#### Steps to Compute:
1. **Compute the z-test statistic.**
- \(Z = \)
- *(Round to two decimal places as needed.)*
2. **Compute the p-value.**
- \( \text{P-value} = \)
- *(Round to three decimal places as needed.)*
3. **Decision:**
- Reject \(H_0\) or do not reject \(H_0\) and interpret the conclusion. Choose the correct answer below.
**Note:**
Type the terms of your expression in the same order as they appear in the original expression. Round to four decimal places as needed.
