The figure to the right shows the results of a survey in which 1004 adults from Country A, 997 adults from Country B,
999 adults from Country C, 1000 adults from Country D, and 995 adults from Country E were asked whether national
identity is strongly tied to birthplace.
National Identity and Birthplace
People from different countries who believe national
identity is strongly tied to birthplace
Country A
31%
Country B
18%
Country C
23%
Country D
55%
Country E
10%
Construct a 95% confidence interval for the population proportion of adults who say national identity is strongly tied to birthplace for each country listed.
The 95% confidence interval for the proportion of adults from Country A who say national identity is strongly tied to birthplace is (☐.) -
(Round to three decimal places as needed.)
ch 15 end. 5: A marketing research firm wishes to study the relationship between wine consumption and whether a person likes to watch professional tennis on television. One hundred randomly selected people are asked whether they drink wine and whether they watch tennis. The following results are obtained:
With a view to study whether the working condition in a factory had any
influence on the frequency of accidents, a researcher collected and tabulated the accident
data as follows:
No. of Accidents
Working Condition
Total
Less
More
Good
280
80
360
Bad
120
120
240
Total
400
200
600
Using Yule's methodology, calculate the coefficient of association between the number of
accidents and the working condition in the factory. What inference would you draw from the
resull ?

We would like to use this factor as one predictor to explain a response y . Consider the method of coding the factor as two indicator variables: 21 = 1 if answer = 0 if answer -1 if answer = Undecided = Yes, No, 22 = 0 if 1 if -1 if Yes, answer = answer = No, answer = Undecided and use a model of the form Yi = Bo + B₁z1i + B₂ Z2i + Ei For a model of this form, Calculate the E(y) for the respondents who answer Yes, No and Undecided respectively?arrow_forwardG.324.arrow_forward
- In a previous practice assignment, you learned about a study in which volunteers (who were all around 30 years of age) from the Chicago area wore light sensors to measure their exposure to sunshine. It was found that those who experienced more daylight had lower body mass indexes (BMIs). The study was observational. It was not an experiment, so conclusions about cause and effect could not be made. Let's redesign the observational study described above into an experimental study.arrow_forwardch 15 end. 6: In the book Business Research Methods (5th ed.), Donald R. Cooper and C. William Emory discuss studying the relationship between on-the-job accidents and smoking. Cooper and Emory describe the study as follows: Suppose a manager implementing a smoke-free workplace policy is interested in whether smoking affects worker accidents. Since the company has complete reports of on-the-job accidents, she draws a sample of names of workers who were involved in accidents during the last year. A similar sample from among workers who had no reported accidents in the last year is drawn. She interviews members of both groups to determine if they are smokers or not.arrow_forwardpls answer G on paperarrow_forward

In a 3 x 2 x 2 factorial design, there are 3 possible interactions in total.arrow_forwardA special education teacher did research on whether or not there is a relationship between the number of students in his class and the number incidents of “acting out” behaviors exhibited by the autistic students in the classroom. He collects data for a year and aggregates them by month. He obtained the statistics below, r= -.863 R2=.74 b= -1.212294 a= 131.176598 10.) How does the presence of more students affect the incidents in the class? a) as students are added the incidences increase b) as students are added the incidences decrease c) the number of students does not affect acting out d) the number of students caused more incidents How much of the variability of acting out is explained by the number of students in the class?___________arrow_forward
