Here we are testing that subject who do or who do nat participate in a sports have different mean syboli blood pressure.
This is our Ho.
First look at the table, Analysis of variance.
In that table the F-value is 0.0264 which is <0.05. This implies that it is statistically significant.
Now the R-square is 0.2337 means that approximately 23% of the variance is accounted by the model.
The t-test psa is equal to 0.0264 and it is statistically significant.
The coefficient of psa is 0.06767 meaning that one unit increase in psa 0.06 units increase in volume.
