Set a flag at the start, use a while loop based on it, unset it once you are happy all is well.
Code:
my $redo=1;
while ($redo) {

  <ask your questions>

  print "Are these statements correct y or n ?\n";
  my $ans=<>;
  if ($ans =~ m/n/i) {
    print "No\n"; 
  } else {
    $redo=0;
  }
}

You don't need the 'm' in 'm/n/i' by the way, because you are doing a readline (<>) you're parsing a single line by definition.
