Prompt: in the tutorial, we calculated the average trust in others for France and visualized it. Using instead the variable ‘Trust in Parliament’ (trstplt) and the country of Spain (country file provided on course website), visualize the average trust by survey year. You can truncate the y-axis if you wish. Provide appropriate titles and labels given the changes. What are your main takeaways based on the visual (e.g., signs of increase, decrease, or stall)?

Answer:From 2002 to 2004, there was an increase in the avergae trust in
parliament in Spain, marking the highest 3.6 in 2004. After 2004 there
was decrease in the trust in parliament until 2012, where it slowly
started to increase again until 2018. After 2018 the average trust in
parliament dropped again.Therefore, the average trust in parlianment in
Spain was the highest in the early 2000, began to gradully decline and
then stalled since 2012.
Task 2 Provide answer only.
Prompt and question: Based on the figure we produced above called task2_plot, tell us: what are your main takeaways regarding France relative to Italy and Norway? Make sure to be concrete and highlight at least two important comparative trends visualized in the graph.
Answer: France had more citizens saying yes to feeling closeness to a party by cohort during 1920 to 1950. During that time, Italy and Norway had less citizen saying yes, it was on a gradual decrease. Despite France’s increasing trend of citizens saying yes, it dropped after 1950, from 0.60 to 0.23. France’s decrease was more immediate compared to Italy and Norway’s slow decrease in the amount of citizens agreeing to the feeling closeness to a party by cohort.
Task 3 Provide code and answer.
Question: What is the marginal percentage of Italian men who feel close to a particular political party?
