2. Replace the value of y with a “3” if price is greater than or equal to “6342”. How many cars have a price greater than “6342”?

3. Replace the value of y with a “2” if price is greater than “4195” and less than “6342”. How many cars have a price between “4195” and “6342”?

4. The code below creates a global called pack that equals “1”. Complete the code so that if $pack == 1 the code prints “Setup mode: running installation/setup steps…” and if $pack doesn’t equal “1” then the code prints “Run mode: skipping setup and continuing with the analysis.” Set $pack to something other than “1” and run the code again.

	global   pack  1

	if XXX == y {
		
	}
	else {

	}

5. Update your code above by adding an else if statement that prints “Update mode: updating ado files…” if $pack == 2
