Question 1 [Total: 13 marks] A group of students investigated whether how long an immigrant has lived in Country X would predict the individual's sense of belonging in Country X. Sense of belonging was measured on a 9-point scale, with higher scores representing higher sense of belonging in Country X. The data collected are shown in the table below: Years lived in Country X Sense of belonging Individual #1 20 9 Individual #2 2 1 Individual #3 7 g Individual #4 10 8 Individual #5 12 7 Individual #6 4 6 a. By hand calculation (i.e., without using statistical software in any step), construct the unstandardised regression equation using the data in the table above to calculate the intercept and regression coefficient. Show your calculation steps and write the regression equation in terms of the numerical values of its coefficient and intercept. [11 marks] b.
