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.
