Is there a linear relationship between a person's diastolic and systolic blood pressures? To study this, researchers gathered a simple random sample of blood pressure

Is there a linear relationship between a person's diastolic and systolic blood pressures? To study this, researchers gathered a simple random sample of blood pressure measurements (in millimeters) from 12 healthy patients.

At the 5% significance level, test the claim that systolic blood pressure and diastolic blood pressure have a linear relationship.

Hypotheses: H0: Slope and Correlation are both zero H1: Slope and Correlation are both not zero Results: What is the correlation coefficient? Use 4 decimal places in answer. r = What percent of the variation of absences are explained by the model? Round to nearest hundredth percent (i.e. 65.31%). R2= What is the equation for the regression line? Use 2 decimal places in answers. Diastolic = (Systolic) + State the p-value. Round answer to nearest hundredth percent (i.e. 2.55%). p-value = Conclusion: We sufficient evidence to support the claim that the correlation coefficient and slope of the regression line are both statistically different than zero (p 0.05).
