The Federal Aviation Administration (FAA) would like to determine if the average number of minutes that a plane departs late differs between airports LAX, JFK, and ORD. The following data were collected from randomly selected flights and indicate the number of minutes that each plane was behind schedule at its departure. LAX JEK ORD 2 18 32 12 19 20 5 22 15 24 10 25 3 14 30 12 a) Perform ANOVA using a = 0.025 to determine if there is a difference in the average lateness of the flights from these three airports.
• State the Null and Alternative Hypothesis.
• Calculate and report grand mean (17).
• Calculate and report each location mean (X;).
• State the critical value and its degrees of freedom.
• Please solve the problem by hand and show the calculation steps clearly.
• Please report the final results in the table format as shown in lecture note.
• State your decision and conclusions explicitly.
b) If warranted, perform a multiple comparison test (Tukey-Kramer Procedure) to determine which pairs are different using a = 0.05.
• Compute the critical range for the Tukey-Kramer procedure.
• Please solve the problem by hand and show the calculation steps clearly.
• State your decision and conclusions explicitly.
c) At the 0.05 level of significance, is there evidence of a difference in the "variation" in flights in these three airports.?
• State the Null and Alternative Hypothesis.
• Please solve the problem by hand and show the calculation steps clearly.
• Please report the final results in the table format as shown in lecture note.
• State your decision and conclusions explicitly.

What is the perimeter of square abcd? units units 28 units 37 units

First to answer all gets a donation question 3(multiple choice worth 1 points) (04.01 lc) which of the following levels is lower than cells in the hierarchy of organization of living things? molecules organs organ systems tissues question 4(multiple choice worth 1 points) (04.01 lc) which of these represents an individual form of life such as an animal, plant, or single-celled life form? organ organism organ system tissue question 5(multiple choice worth 1 points) (04.03 lc) what are the green structures inside plant cells where photosynthesis takes place called? chloroplast mitochondrion nucleus vacuole question 6(multiple choice worth 1 points) (04.03 lc) which of the following best matches a part of a living cell with the function it performs? cytoplasm: fluid which carries the nucleus and other organelles vacuole: fluid which carries the nucleus and other organelles cytoplasm: directs all of the cell's activities vacuole: directs all of the cell's activities question 7(multiple choice worth 1 points) (04.03 mc) read the table below. organelles of plant cells present in both plants and animals present in plants but not animals small in animals but large in plants organelle a organelle b organelle c which statement is most likely correct? organelle a is chloroplast, organelle b is cytoplasm, and organelle c is nucleus. organelle a is mitochondrion, organelle b is cytoplasm, and organelle c is nucleus. organelle a is cell wall, organelle b is chloroplast, and organelle c is mitochondrion. organelle a is mitochondrion, organelle b is chloroplast, and organelle c is vacuole. question 8(multiple choice worth 1 points) (04.03 mc) what will most likely happen in the absence of a nucleus? genetic information will not be transmitted by the cell. energy will not be released during cellular respiration. the cell will not store food, water, nutrients, and waste. the cell will lose its shape and structure.

Three numbers x, y, and z are in the ratio 2: 7: 8. if 12 is subtracted from y, then three numbers form a geometric sequence (in the order x, y–12, z). find x, y, and z. there are 2 sets.
