Data from 10 individuals in renal failure with high blood pressure are shown in the following table. The variable sodium represents salt consumption (in milligrams) and the variable BP represents systolic blood pressure (in mmHG).

Sodium (mg)	7.0	7.2	7.1	7.5	7.2	7.2	7.5	7.3	6.7	6.6
BP (mmHG)	156	169	164	177	192	160	197	191	170	150

a.Create a scatterplot of sodium intake and systolic blood pressure; describe the observed relationship (Note: use the correlation coefficient as a guide for the direction and strength of the relationship.) (Youdo not haveand/ordo not needto submit the scatterplot.)(1 point)

b.Determine the least squares regression line for the data.(2 points)(Keep three decimal places)

c.Interpret theslope coefficientfrom your equation in context (e.g.in terms of sodium and blood pressure). The interpretation has to be clearly elaborated and verbalized.(1 point)

d.What is the predicted blood pressure (BP) for a person from this population that consumes 7.0 mg of sodium per day?(1 point)(Keep three decimal places)
