    For the mean and standard deviation on Q1 it said find x. Does that mean you wouldn't have to put units (£) on the answers?
    In most mark schemes they seem to just ignore units, so it shouldn't really matter if you did or didn't put them on.

    i think i messed up hypotehis one...
    i did h0: u=15.6
    h1 u>15.6
    then used what i had for the value of 19 showed it was greater than 0.01 and concluded...
    do you think i will get any marks for this
    Are you serious? You've lost 8 marks if you've done that

    yeah i know it was stupid but would i not get any for the conclusion being right? and the 2 marker afterwards would i get follow through?

    I'm not 100% but I think the conclusion only gets marks if you did the right calculations earlier. Look at a past paper and see if they say what to do if that happens. As for the follow through maybe, I'm not too sure. Worst case scenario you've lost 10 in total for that bit, best case you've only lost around 6 :/

    Plus whatever is under 1% is your critical region. You should have rejected H1 for the 8 marker and accepted it for the second part. Did you put that?

    Why is finding probability of:

    CC, NICE
    CCC, NICE
    CCCC, NICE
    CCCCC, NICE
    CCCCCC, NICE

    And adding

    incorrect for last question?

    Since it needs to be more than twice before he picks a nice chocolate? I got 2/57 with this.

    Yeah that's what I got, cos it said probably of having to chose at least 2 before getting one he liked? Bit of a dud question I think cos it can be interpreted either way... Nice ocr

    Sometimes they penalise answers given to just 1sf, though if everything else you had done was to a certain number of decimal places or you had written the unrounded answer earlier on then you will probably be fine.
    Yeah I think I would've wrote: "0.0307^2 = 0.0307 x 0.0307 = 0.0009"... also, never knew why zeros after a decimal point are not considered "significant figures" they surely are pretty damn significant.

    Think I've lost marks for the given questions and I put the reason for the mode to be useful because the tourist office would know how many people is most likely would come in that day so they can get the right staff in etc 😂 totally different from what everyone else is saying... I didn't see the mean, so would have lost a mark there too 😣

    I ran out of time with this exam, needed to have longer to check my answers

    I know i already posted this so I'm sorry for posting it again but it's eating away at me and I could really do with an answer ;P
    I messed up my binomial in the question before the hypothesis testing and so did my hypothesis testing with VERY slightly wrong values, however my values were out by such a small amount I got the correct critical region and conclusion in my hypothesis testing.
    I realised my binomial was wrong in the previous question and changed (in an obvious way) just before the end however I didn't have time to change my hypothesis testing values. Will I get error carried forward for this/how many marks will I lose? :O

    To me, the paper seemed incredibly similar to the June 2013 paper, so I'm hoping the grade boundaries are also similar.. What is anyone else's thoughts on this? Definitely harder than last yet imo
