Part A: If the school district wants to award the school that has the most consistent attendance among its students, which high school should it choose and why? Justify your answer mathematically. (5 points) Part B: If the school district wants to award the school with the highest average attendance, which school should it choose and why? Justify your answer mathematically. (5 points)
please wait, I'm pondering...
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
please wait, I ask for help to another helper
I am not got at statistics/probability. I am sorry.
for part B I think that the answer is school X, since school X has the highest mean
oops.. school W not school X
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
ok thanks you guys :) i would date to ask but could dyou help w. one more
