OLS estimation

[na11]

Dear all,

I am testing many hypothesis but I have a doubt about the main conclusion. When I have a model that is considered to be overall statistically significant (prob F-statistics value of nearly 0.000) but some of variables are not significant (prob > 0.10), could I consider that I reject null hypothesis? The model is significant but some variable are not, so it could have wrong conclusions, right?

Thanks in advance.
