Well I suppose that makes sense hey, but luckily it didn't have any of the standard deviation/error in measurement - STOKED!

But.. It says the "weekday rate"? and in order to make up for the missing saturday money ($252) he has to work 14 hours at $18.00, which equals $252?? :( I still don't get it....

I can't see how you got 9 additional hours for question 27 (ii)? I don't get it! I love coming home and checking my answers on the net to see what mark I'll get. I did such a silly mistake, I'm totally kicking myself!! The variation question - I squared it not cubed it!!! ARGHH! I'm also annoyed...

HAHA, Excuse my naivety but what are 'reps'?

I'd like to help you but I have no idea, I hate loans, annuities, interest etc!! Do you know which standard deviation to use - sample or population? WB ASAP!!

This site is like a free "Advice Line" - it's great! I've got another question this time about standard deviation. How do you know wether to use the sample or the population button in figuring out the standard deviation?

Since you've helped me with error in measurement I'll try and help you with financial expectation. It looks long and hard but if you work in sections it's quite simple. What you do is you have a fraction of the event occuring and then you times that by the amount you win/lose..then you add the...

Hey! I think you made a breakthrough, tell me if I've got it right. However many digits there are in the measurement, thats how many zero's there are? If that's right, why do they say "half the smallest unit used"?

But why 0.005? Is that the same for all measurements? I know error in measurement is probably really simple for you and you're probably getting frustrated about how I dont understand it but I still dont get it, sorry! My second post! :)!

YAY, this is my first 'post', how exciting, if I knew how, it would be in pink!! I agree, algebra sucks crap, also so does financial maths but you know which section I found the simplest - area and volume... except for one aspect of it, error in measurement, how do you found "half the smallest...
