• Mechanial Engineering?
  

  Hehe well good luck, my bf does civil, and the maths is killing him lol. Its ok, if you ever need help with maths I’m sure that there are people on this site who can help you with it. But apparently engineering is fun for him, despite how hard it is. I’m sure you’ll do great and love it too

• Chi-square distribution
  

  Oops the second paragraph did not make any sense, here’s what i meant to say
  
  
  So, if your x^2 chi-square is less than critical value then you do not reject Ho.
  Say what you calculated from
  x^2 = [ ( n - 1 ) * s^2 ] / σ^2
  = 0.8

• Chi-square distribution
  

  I could be wrong, but I think that all you have to do is compare your chi-square test, using x^2 = [ ( n - 1 ) * s^2 ] / σ^2 with that of your chi-square critical value. I’m thinking you have to use tables for this or just memorise it:
  
  http://www.itl.nist.gov/div898/handbook/eda/section3/eda3674.htm
  
  So, if your x^2 chi-square critical value then you do not reject Ho.
  Say what you calculated from
  x^2 = [ ( n - 1 ) * s^2 ] / σ^2
  = 0.8
  
  you compare it with the value you get from the table (here we shall use degrees of freedom of 1 at 0.05 significance (see the table))
  
  so the critical value would be 3.841,
  
  so do not reject Ho and conclude that the values are uniformly distributed.
  
  Ummm I think that youre doing a computing subject right? yea but I’m a maths student and suck at computing but yeahhh I’m thinking that all you have to do is compare all your results with 3.841 or whatever your degrees of freedom is.
  
  yeah so if your x^2 is greater than your critical value, then you reject Ho and conclude that the values are not uniformly distributed.
  
  Hopefully i didn’t get you confused.

• Who else loves being a band geek?
  

  [quote Anonymous][quote Debb][quote Anonymous][quote Debb]i was once one, then reality slapped me back into doing something more practical. But from what i can remember being a band geek was fun hehe[/quote]
  
  practical? you learn things in band that prepare you for life better than any other class you could take[/quote]
  
  ohh sorry i didn’t mean to offend anyone. yeahh and i agree with that learning heaps of things in a band, and that’s all good. but yeahh being a band geek no matter how fun it is just wasn’t meant for someone like me unfortunately. . . and i emphasise unfortunately.[/quote]
  
  haha no offense taken. i just didnt really understand where you were coming from. Why didnt it work out?, if you dont mind me asking[/quote]
  
  ahh nahh i dont mind you asking hehe. umm its just i was really confused about what i wanted to do when i was in high school, like if i wanted to go academic or creative arts stuff. yeahh so i sorta missed all the auditions to go to uni and study music because every week i changed my mind about what i wanted to do, but yeahh i semi regret it, coz i miss music so much.
  
  anywho, this is not my post haha. but yeahh i reckon band geeks are cool ;)
