The waiting times (in seconds) are recorded with a single line configuration that feeds four stations and another configuration with indi 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 needed.) - X Waiting times Single Line 389 397 400 410 428 440 444 460 460 460 Individual Lines 254 322 346 374 401 460 460 511 558 602 Print Done Help me solve this View an example Get more help - Clear all Check answer MacBook Air C mylab.pearson.com/Student/PlayerHomework.aspx?homeworkld=622870998&questionld=3&flushed=false&cld=6914052¢erwin=yes STP 231 2022 Spring B 20713 Tran (1) Maryana Tymkiv 03/26/22 10:37 AM E Homework: HW 4: Ch 3 - Measures of Variation Question 3, 3.2.14 HW Score: 65.63%, 5.25 of 8 points Part 1 of 4 O Points: 0 of 1 Save Listed below are foot lengths in inches for 11 randomly selected people taken in 1988.
