Presentation transcript:

 Is there a correlation between an adult’s body mass index (BMI) and their systolic blood pressure…

Number of Adults Systolic Blood Pressure Body Mass Index Data for this hypothesis was gathered using simple random sampling at each group member’s place of employment. Each person was assigned a number and then five unique numbers were randomly selected. The people corresponding to the numbers were assessed in terms of their height, weight, and blood pressure. Number of Adults Systolic Blood Pressure Body Mass Index

Statistics Summary for BMI Mean: Standard Deviation: Range: 18.5 Mode: 21.6 Five-Number Summary: 18, 21.6,23.8, 30, 36.5 Outliers; None Statistics Summary for SBP Mean: Standard Deviation: Range: 79 Mode: 110 Five-Number Summary: 99, 110,121, 132, 178 Outliers: 178

Sample Size: n=30 Correlation Coefficient (R): Standard Deviation: Y Intercept: Slope: P-Value: P<0.015 Critical Value: Equation for line of regression: y = x

 The linear correlation coefficient proves there is not a strong linear relation between the two variables.  The correlation coefficient is greater than the critical value which proves there is a positive correlation between the two variables.  The p value is less than the level of significance which means the null hypothesis should be rejected.

In conclusion, the hypothesis “Is there a correlation between systolic blood pressure and body mass index” should be rejected. There is not a correlation or linear relation between the two variables.
