Hello there! There are more than three subparts in the question. According to our policies can answer only three parts in one question. Kindly find the solution to 99% confidence interval for Country A,B,C. If you have any doubts kindly make a new request for remaining questions. a)The total number of adults in survey from country A n=1014The proportion of people from Country A who believe national identity is strongly tied to birthplace p=0.36 The value of np and n(1-p) are 365.04 and 648.96 which are more than 5 so we use Z distribution to find the confidence interval.The Z critical value for 99% confidence interval is Z=2.576 The 99% confidence interval is calculated as shown belowCI=p±Zp(1-p)nLower limit =0.36-2.5760.36*(1-0.36)1014=0.3212Upper limit =0.36+2.5760.36*(1-0.36)1014=0.3988The 99% confidence interval for proportion of adults from Country A, who believe national identity is strongly tied to birthplace is (0.322, 0.399) rounded to three decimal places.b) The total number of adults in survey from country B n=1012The proportion of people from Country B who believe national identity is strongly tied to birthplace p=0.21 The value of np and n(1-p) are 212.52 and 799.48 which are more than 5 so we use Z distribution to find the confidence interval.The Z critical value for 99% confidence interval is Z=2.576 The 99% confidence interval is calculated as shown belowCI=p±Zp(1-p)nLower limit =0.21-2.5760.21*(1-0.21)1012=0.1770Upper limit =0.21+2.5760.21*(1-0.21)1012=0.2429The 99% confidence interval for proportion of adults from Country B, who believe national identity is strongly tied to birthplace is (0.177, 0.243) rounded to three decimal places. c)The total number of adults in survey from country C n=1023The proportion of people from Country C who believe national identity is strongly tied to birthplace p=0.25 The value of np and n(1-p) are 255.75 and 767.25 which are more than 5 so we use Z distribution to find the confidence interval.The Z critical value for 99% confidence interval is Z=2.576 The 99% confidence interval is calculated as shown belowCI=p±Zp(1-p)nLower limit =0.25-2.5760.25*(1-0.25)1023=0.2151Upper limit =0.25+2.5760.25*(1-0.25)1023=0.2848The 99% confidence interval for proportion of adults from Country C, who believe national identity is strongly tied to birthplace is (0.215, 0.285) rounded to three decimal places.

Contingency Table

A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.

Binomial Distribution

Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.

Question

Need 99% interval for all five countries.

The figure displays the results of a survey conducted among adults from five different countries to determine if they believe national identity is strongly tied to birthplace. The survey included 1,014 adults from Country A, 1,012 adults from Country B, 1,023 adults from Country C, 1,014 adults from Country D, and 996 adults from Country E.

The accompanying table titled "National Identity and Birthplace" summarizes the percentage of adults in each country who agree that national identity is strongly tied to birthplace:

- Country A: 36%
- Country B: 21%
- Country C: 25%
- Country D: 55%
- Country E: 10%

Task: Construct a 99% confidence interval for the population proportion of adults who believe national identity is strongly tied to birthplace for each country listed.

Example: The 99% confidence interval for the proportion of adults from Country A who believe national identity is strongly tied to birthplace is ( [ ] , [ ] ). (Round to three decimal places as needed.)
