Direction: In the following question two statements, one labeled as the ‘Statement (I)’ and the other as ‘Statement (II)’. You are to examine these two statements carefully and select the answers to these items using the codes given below:
Statement (I): For random error with normal distribution, probable error = ±0.6745 σ, where σ is the standard deviation.
Statement (II): Probable error is the error value where there is a 50% chance that any observation has a random error no greater than ±.
