Times for a surgical procedure are normally distributed. There are two methods. Method A has a mean of 35 minutes and a standard deviation of 4 minutes, while Method B has a mean of 39 minutes and a standard deviation of 20 minutes.

(a) Which procedure is preferred if the procedure must be completed within 35 minutes? Method A, Method B, or Either?

(b) Which procedure is preferred if the procedure must be completed within 45.0 minutes? Method A, Method B, or Either?

Answer:-

Since , chance ( probability value) of surgical procedure completion by Method A is more than by Method B. Hence, we prefer Method A in all the three cases (a), (b) & (c).
