Answer:
Method A.
Step-by-step explanation:
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.
