4. Gallup conducted the following poll about immigration policy proposals from June 1 to 13 2018, using a random sample of 5,000 U.S. adults. The results are below. Americans' Views on Four Immigration Policy Proposals % Strongly favor % Favor % Oppose % Strongly oppose % No opinion Allowing immigrants, who were brought to the U.S. illegally as children, the chance to become U.S. citizens if they meet certain requirements over a period of time 40% 43% 11% 4% 1% Banning "sanctuary cities" by requiring local governments to cooperate with U.S. agencies trying to enforce federal immigration laws 27% 23% 22% 24% 4% Ending programs by which legal immigrants can sponsor relatives living abroad to move to the U.S. as permanent legal residents 14% 31% 30% 22% 2% Significantly expanding the construction of walls along the U.S.-Mexico border 24% 17% 23% 34% 2% GALLUP, JUNE 1-13, 2018 a. Is the value 40% of national adults who strongly favor allowing immigrants, who were brought to the U.S. illegally as children, the chance to become U.S. citizens a parameter or statistic? Explain how you know. b. Check the normality conditions for the percent of national adults who strongly favor allowing immigrants, who were brought to the U.S. illegally as children, the chance to become U.S. citizens. Since the population proportion is unknown, we can use the sample proportion to calculate. (Hint: use np 2 10 and n(1 - p) 2 10). Is it reasonable to use a normal approximation in this situation? c. Construct a 95% confidence interval to predict the true proportion of national adults who strongly favor allowing immigrants, who were brought to the U.S. illegally as children, the chance to become U.S. citizens. d. Write a sentence interpreting the confidence interval you found in part c. Your explanation should explain what the 95% represents, and explain the population you are making the prediction about
