Question
Suppose the Humane Society claims that 30% of U.S. households own cats. You believe your community is different than the U.S. percentage. To test the claim, you take a simple random sample of 300 households and find that 38% own cats. Test at 10% significance. **Hypotheses:** - Null Hypothesis (H₀): \( p = 0.30 \) - Alternative Hypothesis (Hₐ): \( p \neq 0.30 \) **How many successes were there?** - (Not filled in, but can be calculated as 38% of 300, which is 114 successes.) **Test Statistic:** - (Not provided in the image.) **P-value:** - (Not provided in the image.) **Did something significant happen?** - Significance happened **Select the Decision Rule:** - Reject the Null **Conclusion:** There is enough evidence to conclude that the proportion of households that own cats in your community is different than the national proportion.
