One surgical procedure has a mean of 6.1 hours with a standard deviation of 1/2 hour. An alternative procedure has a mean time of 6.0 hours with a standard deviation of 4 hours. Based solely on these descriptive statistics, which procedure appears preferable?A) procedure 1 because its time is much more predictable.B) procedure 2 because its time is much more predictable.C) procedure 2 because its time is significantly shorter.

Step 1
Procedure 1 has a mean time of 6.1 hours and Procedure 2 has a mean time of 6.0 hours. The difference is only 0.1 hour, which is not significant. Show more…

You hurry to the local emergency department in hopes of immediate, urgent care, only to find yourself waiting for what seems like hours. The manager of the large emergency department believes that his new procedures have substantially reduced the wait time for the average urgent care patient. He initiates a study to evaluate the wait time. The records of 18 randomly selected patients seen since the new procedures were put in place are checked, and the time between entering the emergency department and being seen by urgent care personnel was observed. The mean wait time was 17.82 minutes with a standard deviation of 5.68 minutes. Estimate the mean wait time using a $99 \%$ confidence interval. Assume that wait times are normally distributed.
Inferences Involving One Population
Inferences about the Variance and Standard Deviation
The mean of the waiting times in an emergency room is 80.2 minutes with a standard deviation of 10.5 minutes for people who are admitted for additional treatment. The mean waiting time for patients who are discharged after receiving treatment is 120.6 minutes with a standard deviation of 18.3 minutes. Which times are more variable?
