Answer:

H0: pF=0.55,pB=0.22,pBG=0.10,pI=0.07,pNG=0.06

Ha: At least one of the proportions is different.

Explanation:

This is a GOF test which means H0 is the expected values which are given to us in this case. If we were to reject H0, it would mean that most observed values are different than expected which would mean there is at least one proportion that is different.
