Answer:
a. Identify the population of interest in this study. 
- all the population of the country
b. Identify the sample for the study. 
- 50 adults (the ones that were surveyed)
c. Identify the parameter of interest in the study. 
- the parameter of interest is the people that believe that coffee shops are overpriced
d. Find and interpret a 95% confidence interval for the parameter of interest.
z score for a 95% confidence level = 1.96
margin of error (E) = z score x √{[0.4(1 - 0.4)] / 50} = 1.96 x 0.069282 = 0.13579
95% confidence level interval: 
0.4 - 0.13579 = 0.26421 
0.4 + 0.13579 = 0.53579 
- 95% confidence interval (0.26421 , 0.53579)
 
        
             
        
        
        
222,702 rounded to the nearest ten thousand would be 220,000
