For solving this question we need to find out the z-scores for both methods,
Since, the z-score formula is,

Where,
is mean,
is standard deviation,
Given,
For method A,


Thus, the z score for 34 is,

While, for method B,


Thus, the z score for 34 is,
,
Since, 
Hence, method A is preferred if the procedure must be completed within 34 minutes.
