Hello @Buddhima,
I think you had the question because in your second bullet point it mentioned p=0 two times. However, in my lab file, I do not see them:
Therefore, to me, there might be something wrong with your lab file. If you would like to get a latest copy of the lab file, follow these instructions which will ask you to rename your current file before the system can write a new one to your account.
Without the p=0 there, and with the latest version of the lab, I believe you can clear your question by reading the lab again?
Cheers,
Raymond
PS: the labβs section 2.3.2 told you what label value is used for representing an anomalous example.
