The conclusion was that an atom has a nucleus (center) with a positive charge.
It demonstrated that there is positively charged nucleus and the atom is mostly empty spaced.
What are the 'statements' and which 'experiment' is meant to be 'supported' in this question.
positive
The conclusions were that the nucleus in an atom must:- (1) Be positive as it repelled the positive alpha-particles (2) Have a high mass, as the deflections were massive (3) Be very small as only a few of the particles were deflected
Rutherford used the gold foil experiment to figure out that an atom had charged particles in the nucleus

positive
The nuclear atom was discovered by Ernest Rutherford. He did it with a gold foil experiment.
That the mass of an atom is mostly located in a small nucleus.
Opinions vary. The discovery of the atomic nucleus ("most of the atom is empty space")
The conclusions were that the nucleus in an atom must:- (1) Be positive as it repelled the positive alpha-particles (2) Have a high mass, as the deflections were massive (3) Be very small as only a few of the particles were deflected
He discovered that the atom was mostly made up of empty space.

Ernest Rutherford
Ernest Rutherford did this experiment in 1909 with Hans Geiger and Ernest Marsden.
