Median Quartile Percentile

1. Answering the 3 question correctly * Only question 1 has three parts. I need to see the work for each answer ( The steps and formulas ) look for how the answers they should be formatted at the proffesor set at the discussion.  Discussion Board 2 – Median Quartile Percentile (Location) & Chebyshev’s & Z-Values 1. Using the following numbers: 15 17 22 27 29 34 37 45 49 51 53 56 59 Find the Median 1st Quartile and the 65th percentile (No Rounding – Exact answer). * When computing quartiles and percentages use the exact method from the notes. This will be true for the exam as well not all calculators use the exact method. * 2. The average amount of time an airplane spends in the air during the day is 8.7 hours with a standard deviation of 2.3 hours. What is the minimum proportion(percentage) of airplanes that will spend between 4.79 hours and 12.61 hours in the air on any given day? (round your final answer to 4 decimal places and express as a percentage – ex. .6123 expressed as 61.23%) 3. The average amount of time it takes to board an airplane is 26.3 minutes with a standard deviation of 5.2 minutes. If you have a z-score of -1.3 what time does this represent? (round your final answer to the nearest hundredth – ex. 31.05 minutes) This Discussion Board is Due Monday February 1st by 11PM. When you answer the question put the answers in this and label like this: 1A. Median: 1B. 1st Quartile: 1C. 65th Percentile: 2. 3. Value of Discussion Board = 5 1 point for each question.
