Simple Regression Results Interpretation
Null and Alternative Hypotheses
The dependent variable (y) is injuries (severity of injuries) while the independent variable (x) is hours of training. The study seeks to determine whether the hours of training are a significant predictor of the severity of injuries in case one gets hurt playing football. The regression equation is:
Y = a + bx
Where Y is the dependent variable, x is the independent variable, a is the y-intercept and b is the slope of the line.
The null and alternative hypotheses are:
H0: b = 0 (x has no effect on y)
HA: b ? 0 (changes in y are due to changes in x)

p value = 0.011
significance level (alpha) = 0.05
R2 =0.21 (21%)
b = -0.125
a = 6.8473
The regression line Y is given by:
Y = 6.8473 - 0.125x
