Need help with One Questions

[Mark121]

I have six variables that can influence countries GDP growth. These are YearsSchool, RevCoups, Assassin,
RGDP60, Tradeshare, and Oil export.

Question.... Test, whether, taken as a group, YearsSchool, RevCoups, Assassin and
RGDP60 can be omitted from the regression. Hint: specify the hypotheses to be
tested and estimate the appropriate restricted model.

I am using Eviews 5. Can any one suggest how can I approach this question. Which Test I can use.

Please advise.

Thanks
