A hospital experiment involves two different waiting line configurations for patients arriving for admission The waiting times (in seconds) are recorded with a single line configuration that feeds four stations and another configuration with individual lines at the four stations Find the coefficient of variation for each of the two samples, and then compare the variation Click the icon to view the waiting time data Find the coefficient of variation of the single line data set % (Type an integer or a decimal rounded to one decimal place as Waiting Times Single Line 390 394 400 409 425 439 445 464 464 464 Individual Lines 250 322 350 373 400 463 463 512 560 599
