The correlation coefficient of this data is 0.1058 which means the data is a weak positive relationship. This is also a weak positive relationship as the correlation coefficient is between 0 and 0.33 like the
This indicates that the Covid - 19 cases and mortality rate in third world countries in 2020 are related in first independent variable we looked at. This tells us the same results of the murder rates and mortality
some way, however they are not strongly related. The slope of the line of best fit is -0.086. This means rate although being related in some way, it isn't strong. The slope of the line of best fit in this case is
that for every 0.086% decrease in Covid - 19 cases, the percentage of mortality rate in third world countries 1.04 meaning that for every 1.04% increase in murder rates, the mortality rate goes up by 1 in the third
will decrease by 1. The y - intercept of this line of best fit is 2.53 which means that if Covid - 19 world countries in 2020. The y - intercept of this line of best fit is 11.4 which means if the murder cases
cases were 0, the mortality rate in these third world countries in 2020 would be 2.53. were 0, the mortality rate in these third world countries in 2020 would be 11.4%.
