I've been trying to solve this exercise for a long time. I know that is not that dificult.

However i cant remember how to do it.

Ho = 0

H1 dif 0

1977 observations.

I was wondering that to calculate the F-test i should have the standard error for the Y variable, but i dont have.

Also, i was expecting to do sd1/sd2 to get my F and make a comparison using the F table, but i am not sure if this is right.

Thanks in advance.

Calculate the F-test statistic for this equation and use it to perform a test for the null hypothesis that the slope coefficient is equal to zero
