2. Western Airlines merged with a smaller airline recently. Every day since the merger, a random sample of 30 Western flights has been analyzed every day. A flight that takes off more than 10 minutes after its scheduled departure time is considered to be late; otherwise, it is not late. Western's performance over the past 10 days is shown in the table below. Day 1 2 3 4 5 6 7 8 9 10 #Late Flights 4 2 5 9 2 3 3 1 2 8 For 3-sigma control limits, construct the appropriate control chart? No plotting of the chart is required. Has Western Airlines' on-time performance been in-control over the last 10 days? Explain briefly.
