...maybe before tomorrow sarevok?

 

[sarevok]

this is murray's answer to one of those find the probability of a type b error questions

i believe this is question e)

i don't understand his working, so if some one smart i.e. lainee can explain it that would be good (sorry for shitty mspaint but scanner is broken)

and yes, there is a typo with brackets

edit: also, the upper crit value equals 163

Murray is an arseclown.

I hate him so much.

I gave him the biggest roasting in that student feedback form...

Hahha i did a hypothesis test in the student feedback form:

H0:u=murray is an awesome lecturer
H1:u=murray is crap.
alpha=0.01
Using p-value test, p=0.0000000000069
we thus reject H0.

turns out the attachment didnt upload. too big. ill upload a screen capture of
Q2 part c as people seem to be having a lot of trouble with it. As am i.
There's some i have no idea for.
crap quiz tomorrow

Also how do we calculate the p-value for the second q2?

 

[stazi]

ok I = standard error * tstat

 

[myg0t]

whats the weighting of this quiz?

 

[WaffenssLAH1985]

some diffences appear in my answer
1.in q 1(b), my approach is Ho=90,H1<90, so tobs =-2<-1.6604,reject
2.in q 1(d), my p-value is p(Z>1)=1-0.8413=0.1587
3.q 1(e), my p is p(absolute Z>0.73)=0.2327*2=0.4654
4.in (f), mine is Ho=80, H1>80, tobs is 1.22, the p-value isp(Z>1.22)=1-0.8888=0.1112
