    Hi Folks
    I really need your expertise help this assignment has to be handed in tommorow. I have done the tasks but just need abit of advice and guidance to put the finishing touches to it

    I'm stuck on Task one question 3, the data allocated to me is 2, so xxxx is 176 and yyyy is 3000. I took, 176 - mean / standard deviation. Is this the correct procedure and is the answer correct? If the answe is correct its a negative answer and how do I look this up on the Ztable and the how do i calculate this to see if the process is acceptable?

    I've also attached the copy of the original question and the Z table. Thanks in advance.
