A ✩ The box-and-whisker plot below represents the length, in inches, of 20 trout caught at Raystown Lake in one weekend. 4466619/varlants/5145485/take/5/ 10 Length of Trout (inches) H 15 20 H 25 30 How many trout were less than 20 inches long? Hint: 20 inches is the upper quartile of the box-and- whisker plot. So, 75% of the trout were less than 20 inches long. To find the answer: multiply the percentage (75%) x 20 (the number of inches) We use 75% because that is the Q3 in the data. 25% would be our Q1 and 50% is the median (or Q2).

Continue monitoring the process. A second ten days of data have been collected, see table labeled “2nd 10 Days of Monitoring Reservation Processing Time” in the Data File. Develop Xbar and R charts for the 2nd 10 days of monitoring. Plot the data for the 2nd 10 days on the Xbar and R charts. Is the reservation process for the 2nd 10 days of monitoring in control? If the control chart indicates an out-of-control process, note which days, the pattern, and whether it is the Xbar or R chart. Based on the X-bar and R Charts that you developed for the 2nd 10 days of data, is the process in control? Group of answer choices No. The X-bar and R Charts are both out of control. No. The X-bar Chart is in control, but the R Chart is out of control. No. The R Chart is in control, but the X-bar Chart is out of control. Yes. The X-bar and R Charts are both in control.
