Question

hospital emergency waiting time. the mean waiting time in an emergency - room is 120 minutes for a standard deviation of 12 minutes for people who are admitted for additional treatment. the mean waiting time for patients who are discharged after receiving treatment is 122 minutes with a standard deviation of 12.9 minutes. which times are more variable? part 1 of 2 calculate the coefficient of variation. round your answers to one decimal place. additional treatment cvar : 10.2% discharged cvar : 10.6% part: 1 / 2 part 2 of 2 the waiting times for the select patients were more variable.

Explanation:

Step1: Recall coefficient - of - variation rule

The higher the coefficient of variation (CVar), the more variable the data.

Step2: Compare CVars

The CVar for additional treatment is 10.2% and for discharged patients is 10.6%. Since 10.6%>10.2%.

Answer:

discharged
