Find if there is a relationship between education (in years) X and income Y.

x	4	6	8	11	12	14	16	17	20
y	6000	12000	14000	10000	17000	16000	13000	16000	19000

Make sure that THREE of your posts for the week are Statistical in nature AND a direct response to the problems given in the discussion

Expert Solution

To find the relationship between x and y we need to plot a scatter-plot between variables which is plotted using the software as:

From the scatter-plot, we can say that there is an almost positive correlation around 0.70.

To find the accurate correlation we do the following tabulation as:

The correlation is calculated as:

based on the data provided the calculation is:

Now from the calculation we find that the exact correlation is 0.77 hence we can say that there is a positive correlation between the variables.
