Briefly glanced over what answers I can remember and seems mostly correct although for Q2 b.i. I'm pretty sure the shape of the distribution for May was 'approximately symmetric'.

Yes i was confusing about that ,it looks like approximately symmetric but it also look like negatively skwed , the graph is not that clear So I choose negatively skewed.
