(cl Write down a regression model depicting the relationship between the two variables. Please ensure you explain each symbol used In the model and equation. Question 6 A remarkable fact about the Scottish referendum held in 2014 is that there were some suggestions that there may be a link between poverty and the level of support for independence. The question is whether this view is supported by the available data. Voting data from the referendum is available for each of the 32 Scottish regions. All that remains is to try and come up with a simple measure of economic affluente. House prices seem like a natural starting point. It should cost less to live in less affluent areas and cost more to live in more affluent areas. A prominent housing website in the UK came up with an index (called the Zoopla Z-Index) to measure the average property value in a given area based on current estimates. The figure below shows a plot of the proportion of Yes votes against the zed-index with a regression line fitted by Ordinary Least Squares superimposed. As anticipated the proportion of yes (to independence) votes and the zed-index appear to be negatively correlated - a result which is suggestive of the link between poverty and voting for independence. Results from a regression slope t-test show this to be statistically significant (p=0.021). Figure 6 Proportion of yes votes 120000 140000 160000 180000 200000 220000 240000 260000 Zoopla zed index Based on the information given and Figure 6, you are required to answer the following questions. (a) Determine the dependent and independent variables used in this study. (b) Comment on the scatterplot clearly explaining the relationship between the two variables
