From spring '05 to fall '07, there were 9 statistics questions on each exam across the board. In spring '08 there were 8. I believe fall '08 and spring '09 were the same. Last sitting had a marked drop-off in # of stat questions, and today I counted 6.

Answered 23. Seemed like a very easy test compared to last sitting. There was one poisson question with a normal approximation and i didn't remember to use the continuity correction (i thought about this when i left). I wonder if that turns out to make a difference. i believe it was something like (508.5-430)/79. Im pretty sure I got about 18 correct. I hope this means pass.

what did you guys get for the t-stat question? i got like 15.606 something? it asked for the 5% level, but it was 1-tail, so you had to get the 10% critical value and solve it that way. you also had to figure out was S^2 was, which was too bad.

if you didnt used continuity the answer was still in the range. it asked for at least 508, so it was 1 - P(X<507.5). i got 1- I(.89).

exactly what i got

I tried it both with and without the cont. correction. Made no difference. You're good on that.

Yep!

the order stats question was str8 forward. i got .5 for the variance?

anybody think the markov chain question with 24 out of 50 actuarial candidates becoming fellows in 4 years was kind of ridiculous? not that it was difficult; it just didn't seem realistic/was depressing to me.
