How do I choose one player and give them a sword?

How do I create a script that chooses one random player and gives them a sword, more health and walkspeed?

Also, it needs to teleport them to a position.

Here are some of the basics. You'll have to edit some things in order for it to work, but this is what it would look like for the most part.

function ChoosePlayer() -- declare function
	local players = Game:GetService("Players"):GetPlayers() -- player list
	local plr = players[math.random(#players)] -- random player
	local hum = plr.Character:WaitForChild("Humanoid") -- declare variable for Humanoid
	Game:GetService("ServerStorage"):FindFirstChild("Sword"):Clone().Parent = plr:FindFirstChild("Backpack") -- give sword
	hum.MaxHealth = 200
	hum.Health = (hum.Health / 100) * hum.MaxHealth -- heal the character proportionally
	hum.WalkSpeed = 32 -- change walkspeed
	plr.Character:MoveTo(Vector3.new(0, 0, 0)) -- teleport
	return plr
end

local chosenPlr = ChoosePlayer() -- call function
local msg = Instance.new("Message", Workspace)
msg.Text = chosenPlr.Name .. " was chosen!"
Game:GetService("Debris"):AddItem(msg, 3)
