A country with a fairly large population. You recently performed a poll for the upcoming presidential election. There are two candidates the incumbent candidate and the opposition candidate. You randomly polled some Forsythian voters to determine the likelihood of the incumbent winning. You asked voters if they plan to vote for the incumbent or the opposition in the upcoming election. If they say the opposition you record a 0. If they say the incumbent you record a 1.

- Your younger brother, a fourth form practical geography student wishes to test whether there could be some relationship between annual visits to a local market by all residents surrounding that market. After a well-designed field study he obtains the following figures: Number of visits per year 21 13 19 18 17 17 14 20 10 11 Residence distance from market (KM) 1.0 2.0 3.0 4.0 5.0 6.0 7.0 8.0 9.0 10.0 From the information above, what is the dependent variable and what is the explanatory variable? Using (i) above, obtain the regression equation of Yi on Xi. Hence, estimate the residence distance from the market (in KM) if the number of visits are 16 visits Sketch your results in (ii) above.
