Question: You run a simple linear regression test to determine whether body mass index (BMI) is a statistically significant predictor of systolic blood pressure (SBP). Review
You run a simple linear regression test to determine whether body mass index (BMI) is a statistically significant predictor of systolic blood pressure (SBP). Review the test results below and determine whether each statement is an appropriate conclusion to make based on these findings.
True or false or there is not enough information
The results are statistically significant?
The p-value is .507?
SBP can predict about 50% of the variability in BMI?
There is a strong relationship between these variables?
There is a positive relationship between these variables?
SBP is a significant predictor of BMI?
