Linear Regression Equation and Its Interpretations

Simple Linear regression results:
Dependant Variable : Stoppages
Independent Variable : Temp Variability
Stoppages = 5.740207 - 0.27559829 Temp Variability
Sample Size: 16
R (correlation coefficient) - -0.04475
R-sq = 0.20022592
R-sq = 0.20022592
Estimate of Standard Deviation : 2.0759327

a. What is the correlation coefficient ?
-0.4475
Please check your figure. Correlation coefficient is square root of r-square value.

b. what is the mean?
It means that there is a negative linear relationship between Stoppages and temperature variability. As ...
