hello, here are some hints from mr ng for sampling tut..
for last part of qn 2...
Use GC PLOT to solve. create y1=normal cdf(...)
y2=0.9

he also added something abt e ans (last part) being wrong.. but then later he said correct. whatever, i think it should be sth like reject(142.8)^2 because it's too large. but i'm not sure also.

if you see extra rev qns/assignments pls pass to me.. think i'm missing 1/2 of rev extra qn 3 n sampling assignments.=.=
