dults aged 18 years old and older were randomly selected for a survey on obesity. Adults are considered obese if their body mass index (BMI) is at least 30. The researchers wanted to determine if the proportion of southern women who are obese is less than the proportion of southern men who are obese. The results are shown in the table below. Test at the 1% level of significance. Number who are obese Sample size Men 42,773 155,525 Women 67,176 248,775 a.State the distribution to use for the test.

The 2004 General Social Survey asked a random sample of 977 adult Americans how often they feel rushed, with three options to choose from: always, sometimes, and never. The sample result was that 304 of the 977 people responded "always." Calculate the value of the test statistic by hand. Round the sample proportion and the hypothesized value of the proportion to THREE decimal places. Round the final answer to TWO decimal places.
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.
