If the p-value is significant (for example <0.05) then use fixed effects, if not use random effects. Hoechle, D. (2007). /Text Example 1. Again, the p value is large so do not need to use time-fixed effects in this model.

After constructing a fixed-time effects model, we can run some tests to see whether this is needed. To reject this, the p-value has to be lower than 0.05 (95%, you could choose also an alpha of 0.10), if this is the case then you can say that the variable has a significant influence on your dependent variable (y).
