Use 2010 data for all following questions.
What is the correlation between mortality rate and GDP per capita?
What kind of variable is mortality rate and GDP per capita? What is dependent variable here and what is independent variable?
What kind of sampling used here?
Show frequency distribution and relative frequency distribution table for mortality rate. Mortality rates 0-25, 26-50, 51-75, 76-100, 101-114, draw a table and show frequency, relative frequency, and percentage of mortality rate? Draw histogram of relative frequencies for mortality rate.
If it is possible show on a stem and leaf plots.
What is the shape of distribution? Is it skewed to left or skewed to right?
What is the means, standard deviations, min and max; and the correlations among variables?
What kind of hypothesis (null, alternative)is this?
Find the test statistics if possible.
Construct a scatterplot.
Run a regression to obtain the coefficients; and explain what the coefficients mean for the particular research question of interest, and their statistical significance.
