I'm doing question C5.1 in Wooldridge's econometrics textbook. The question asks you to test the hypothesis H0:intercept equals.5 against H1: intercept does not equal .5. Wooldridge instructs you to do so by running a regression of the dependent variable on a constant, which I've done. I'm then trying to use linearHypothesis to test the H0 that the intercept is equal to .5, but something seems to not be working.

I input the following code

install.packages('wooldridge')
library('wooldridge')
data(pntsprd)
reg<-lm(sprdcvr~1,data=data)
H0<-("Intercept"=0.5)
linearHypothesis(reg,H0)

and get this output:

Linear hypothesis test

Hypothesis:
0.5 ((Intercept) = 0

Model 1: restricted model
Model 2: sprdcvr ~ 1

2    552 138.12  1    146.88 587.01 < 2.2e-16 ***

What am I doing wrong?
