    I'm not sure, nevertheless I think school Z, since a lower \sigma, means a more narrow distribution, furthermore school X and school Y have a lower "Low" values than school Z

    for part B I think that the answer is school X, since school X has the highest mean

    To me, for a) I choose Z since the \(\sigma \) is smallest. That means the consistent is highest. One more reason, for L = 130 , and H = 180, we can see that the fewest day the student attendance is higher than other while the highest day is the same with others. for b) I choose W (the reason is its mean is highest, like what you choose)

    But, don't rely on me. I am not good at statistics.

    yes! I also used the value of \sigma, since the value of \sigma tells us the shape of the distribution
