**Hypothesis Testing for Cat Ownership in U.S. Households**Suppose the Humane Society claims that 30% of U.S. households own cats. You believe your community is different from the U.S. percentage. To test the claim, you take a simple random sample of 300 households and find that 30% own cats. Test at 10% significance. Round to the fourth.- **Null Hypothesis (\(H_0\))**: - Select an answer [ ] - Select an answer [ ] - Select an answer [ ]- **Alternative Hypothesis (\(H_A\))**: - Select an answer [ ] - Select an answer [ ] - Select an answer [ ]**Questions and Fields to Fill:**1. **How many successes were there?** - [Input field]2. **Test Statistic:** - [Input field]3. **P-value:** - [Input field]4. **Did something significant happen?** - Select an answer [ ]5. **Select the Decision Rule:** - Select an answer [ ]6. **There [ ] enough evidence to conclude** - Select an answer [ ] **Explanation**: In this exercise, you are asked to test a claim about cat ownership in U.S. households by using hypothesis testing. You'll need to state and test both the null and alternative hypotheses, calculate the test statistic and the p-value, and finally decide if there is enough evidence to support the claim.

According to a report on consumer fraud and identity theft, 24% of all complaints for a year were for identity theft. In that year, Connecticut had 861 complaints of identity theft out of 3484 consumer complaints. Does this data provide enough evidence to show that Connecticut had a higher proportion of identity theft than 24% ? Test at the 10% level. State the hypotheses. Ho: P? O Ha: P ? Calculate the test statistic. Round to four decimal places. p = Calculate the standardized test statistic. Round to three decimal places. z = Find the p-value. Round to four decimal places. p-value = State your decision. O Since the p-value is greater than .10, reject Ho. O Since the p-value is less than .10, fail to reject Ho- O Since the p-value is greater than .10, fail to reject Ho. O Since the p-value is less than .10, reject Ho. Interpret the results.

Another question asked for a ranking of the condition of the road, based on the type of road. For the road types of interstate highway, U.S. highway, state (“M") highway, and local roads, residents were asked to evaluate the current condition, with choices of good, bad, or neutral. Researchers wish to evaluate if there is some relationship between the type of road and the road condition. This is a O Hypothesis test O Confidence interval For One proportion One mean O Paired mean O Difference in two means O Slope for a linear relationship O Chi-square goodness-of-fit O Chi-square test of independence
Suppose a survey of 931 business owners found that 23% bought flood insurance. Which part of the survey represents the descriptive branch of statistics? Make an inference based on the results of the survey. Choose the best statement of the descriptive statistic in the problem. O A. Most business owners do not buy flood insurance. B. There is no association between business owners and buying flood insurance. OC. 931 business owners were surveyed. O D. 23% of business owners in the sample bought flood insurance. Choose the best inference from the given information. OA. 23% of business owners in the sample bought flood insurance. OB. 931 business owners were surveyed. OC. Most business owners do not buy flood insurance. D. There is no association between business owners and buying flood insurance.

Sample surveys on sensitive issues can give different results depending on how the question is asked. A University of Wisconsin study randomly divided 2400 respondents into three groups. All participants were asked if they had ever used cocaine. One group of 800 was interviewed by phone; 21% said they had used cocaine. Another 800 people were asked the question in a one-on-one personal interview; 25% said “Yes.” The remaining 800 were allowed to make an anonymous written response; 28% said “Yes.”101. Was this an experiment or an observational study? Justify your answer.2. Make a two-way table of responses about cocaine use by how the survey was administered.3. Are the differences between the three groups statistically significant? Give appropriate evidence to support your answer

According to a report on consumer fraud and identity theft, 20% of all complaints for a year were for identity theft. In that year, California had 724 complaints of identity theft out of 3466 consumer complaints.

Indicate the statistical test you would conduct. Respondents in a survey of 1,000 households were asked about their travel history. Specifically, they were asked how often they have been to Europe in the past five years (using a ratio scale). People were also classified by interest type (art-lovers, food-lovers, or sports-lovers). The question is whether interest type influences travel history. Two-sample t-test Paired sample t-test One-way ANOVA none of those QUESTION 6 What is the corresponing alternative hypothesis for the scenario in question #5? The three interest types do not differ with regard to the number of times they have been to Europe in the last five years. Interest type and travel to Europe are not related. The number of times people have been to Europe does not depend on interest type. The three interest types differ with regard to the number of times they have been to Europe in the last five years.
