QuestionHospital Emergency Waiting Times The mean of the waiting times in an emergency room is 124 minutes with a standard deviation of 8.9 minutes for people who are admitted for additional treatment. The mean waiting time for patients who are discharged after receiving treatment is 105 minutes with a standard deviation of 9.3 minutes. Which times are more variable?
Part: $0 / 2$ $\square$
Part 1 of 2
Calculate the coefficient of variation. Round your answers to one decimal place.
Additional treatment CVar : $\square$ $\%$
Discharged CVar: $\square$ \%

Studdy Solution
Compare the coefficients of variation:
- Additional treatment CVar: $7.2\%$ - Discharged CVar: $8.9\%$
The discharged group has a higher coefficient of variation, indicating more variability in waiting times.
The coefficients of variation are:
Additional treatment CVar: $\boxed{7.2\%}$
Discharged CVar: $\boxed{8.9\%}$
