The success of an airline depends heavily on its ability to provide a pleasant customer experience. One dimension of customer service on which airlines compete is on-time arrival. The tables below contains a sample of data from delayed flights showing the number of minutes each delayed flight was late for two different airlines, Company A and Company B. Company A Company B 34 46 59 43 30 3 32 42 85 30 48 110 50 10 26 70 83 78 27 70, 27 90 38 52 76 52 Ho: H1 - H2 - 0 H₂: H₁-H₂0 Ho: H3 - H2 =0 H₂H₁-H₂=0 Hỏi hội đảng 50 H₂: H₁-H₂>0 Ho: Hi-H2 <0 H₂: H₁-H₂ = 0 Ho: M1-1₂ 20 H₂: H₂H₂ <0 64 42 32 67 106 44 28 38 84 74 min min (a) Formulate the hypotheses that can be used to test for a difference between the population mean minutes late for delayed flights by these two airlines. (Let ₁ = population mean minutes late fo delayed Company A flights and ₂ = population mean minutes late for delayed Company B flights.) 45 33 50 64 42 36 34 64 64 (b) What is the sample mean number of minutes late for delayed flights for each of these two airlines? Company A Company B (c) Calculate the test statistic. (Round your answer to three decimal places.)
