PLEASE ANSWER ALL QUESTIONS 1. What is the critical value between the accept and reject regions (the decision rule) in the following hypothesis test? Passenger trains for commuters strive for consistent on-time arrival. A study is to be conducted on the arrival times at three regional train companies. The samples will measure the average on-time performance of six trains from each group (18 total trains), recording the amount of time the trains are delayed. The study will indicate whether or...

Question 2: [27 miks (a) In the North coast of Oman, on the Al-Batina region - Sohar, the wind has a most peculiar behavior as shown in Figure Q2 a (i). At precisely 06:00, there is a short interval with absolutely no wind. Local peasants set their digital watches by this lull. Wind velocity then builds up linearly with time, reaching exactly 8 m/s at 22: 00. It then decays, again Iinearly; to the moming lull. To simplify the graph...
