For normal distribution, you always assume 50% of the data is lower than the mean and 50% is above the mean. Remember the mean is considered to have a z-score of 0. The table tells us that as the z-score increases, so do the percentage of scores covered. Since the question is asking what is...

um yes so the questions they ask are like WHAT IS THE PROBABILIU FROM 0-whatever.... u take away .5 bc .5 is below the mean, hence bellow 0? idk if that makes sense I hope it does

yeah I get that a lot of people say the same thing... i was complaining abut how old the syllabus was and I wishes I was in year 11 so I could do the new syllabus BUT I TAKE BACK WHAT I SAID :cry: I feel truly sorry that ur doing it through SoN which is extra bad.... is ur teacher Mr McGuire my...

these sample answers are usually really bodge anyway, if ur dfd makes sense and covered the whole q then what is there to loose as long as it is 'substantially correct'

tps is the best

got it okay thank u

was there actual feedback on the paper or what do they just give u the score u got?

so when does scaling come into play? when your final atar is calculated?

whattt no way. so you never actually really know your true mark in the exam unless u pay?

guys when we get our hsc marks is that RAW or is that after scaling?

yeah tbh all that stuff u can just pull out of ur arse and you'll get the full marks after u relate it to the question and explain the effect I guess

that's what I said to myself for trials and did bollocks so not taking any risks... :monkey: :monkey: :monkey:

Heres something that might be of help for you guys... for file stuff :>
