Question 4. Birthrate (the independent variable) and Female Life Expectancy (the dependent variable) values are given for 10 countries below.

  1. Prepare a scatterplot and briefly discuss the pattern: what sort of a correlation (strength and direction-wise) does the scatterplot suggest?
  2. Calculate the values or r and  and interpret these values.

Given here are the data from a dependent variable and two independent variables. The second independent variable is an indicator variable with several categories. Hence, this variable is represented by x2, x3, and x4. How many categories are there for this independent variable? Use a computer to perform a multiple regression analysis on this data to predict y from the x values. Discuss the output and pay particular attention to the dummy variables. y x1 x2 x3 x4 11 1.9...
