The study focuses on constructing a 90% confidence interval for the proportion of all Americans who are in favor of a new Green initiative. The details and questions provided are as follows:"A newsgroup is interested in constructing a 90% confidence interval for the proportion of all Americans who are in favor of a new Green initiative. Of the 559 randomly selected Americans surveyed, 396 were in favor of the initiative. Round answers to 4 decimal places where possible."**Question A:**a. With 90% confidence, the proportion of all Americans who favor the new Green initiative is between ___ and ___.**Question B:**b. If many groups of 559 randomly selected Americans were surveyed, then a different confidence interval would be produced from each group. About ___ percent of these confidence intervals will contain the true population proportion of Americans who favor the Green initiative and about ___ percent will not contain the true population proportion.**Instructions:**- Provide the answers with four decimal places for accuracy where applicable.- While constructing confidence intervals, it is crucial to understand what they imply about the population parameter being studied.

The figure to the right shows the results of a survey in which 1018 adults from Country A, 1025 adults from Country B, 1005 adults from Country C, 999 adults from Country D, and 999 adults from Country E were asked whether national identity is strongly tied to birthplace. Construct a 95% confidence interval for the population proportion of adults who say national identity is strongly tied to birthplace for each country listed.

In a sample of 624 applicants to the Durmstrang Institute of Sorcery, 133 were accepted. Construct a 90% confidence interval for the true proportion of applicants to Durmstrang that are accepted. Does it appear that Durmstrang accepts 20% of their applicants?
In a survey of 508 adults, 317 indicated that emails can be easily misinterpreted. If we wish to construct a 95% confidence interval to estimate the true proportion of adults who believe that emails can be easily misinterpreted we would substitute a. P hat is equal to b. Z is equal to
In Bloomington, they randomly sampled 260 female voters, and 190 male voters. They collected data on the respondent's opinion on an environmental bond issue. We want to know whether there is good evidence that one's gender influences whether a person is for or against the bond issue. Use α = 0.05. For Bond Issue Against Bond Issue Total 52 260 17 190 69 450 Men Women Total a) What is the correct null hypothesis? O Ho: P₁ P2 P3 P4 O Ho: P₁ P2 = P3 P4 O Ho: Gender and Bond Issue Attitudes are Independent. O Ho: Gender and Bond Issue Attitudes are dependent. b) Fill in the expected values, round answers to 1 decimal place.
