Just wondering if anyone here has done the practice class 1 test.?
If so, what answers did you get..
Im slowly working my way through it and so far, ive just finished question 2, but what ive done , is do a joint probability table at the start. Then, they said create one in the last question, so i dont know if i did the first questions right.
These are my answers for q2. can anyone else confirm and/or make suggestions?
i) 0.673
ii) 0.909
iii) 0.557
iv) No.
v)
location in degree (D) Not in Degree (!D) total
parra (P) 419 204 623
notparra (!P) 333 381 714
total 752 585 1337
Hopefully someone can reply, just going a bit muddeled.
