At the mining company you work at, there are 4 haul trucks used to transport rocks from the primary crusher. The haul trucks have had breakdowns in the past month, and you are asked to investigate. There are 3 different crews who operate the haul trucks. Assume a 90% condence for your investigation. The number of breakdowns per crew for each haul truck is shown as follows: Haul Truck Crew A B C D 1 14 7 4 5 2 10 4 3 5 3 5 6 5 3 A. Determine the total number of observations across all crews and all haul trucks: B. Determine v: C. Determine the expected frequencies for A1 ( ) and D3 ( l D. Determine 2&3 E. Determine xiv: F. Are the breakdowns independent from the crew? "yes" or "no" (lowercase, without quotes)
