Cenario 1: an airline wants to select a computer software package for its reservation system. four software packages (1, 2, 3, and 4) are commercially available. the airline will choose the package that bumps the fewest mean number of passengers as possible during a month. an experiment is set up in which each package is used to make reservations for 5 randomly selected weeks. (a total of 20 weeks was included in the experiment.) the number of passengers bumped each week is given below. perform an anova in order to test the difference in mean number of passengers bumped every week by the four packages. package 1: 12, 14, 9, 11, 16 package 2: 2, 4, 7, 3, 1 package 3: 10, 9, 6, 10, 12 package 4: 7, 6, 6, 15, 12

step-by-step explanation:

idk the answer i want to say 10 but then it would be equal so try 9 but then yeah so yeah we love edgen

the answer i believe is 27 units.

step-by-step explanation:

55.44 inches

step-by-step explanation:

part a. assuming a perfectly linear relationship, we can find the slope from the first two data points.

slope = m = (change in rainfall)/(change in years)

= (61.80 -62.33)/(2005 -2004) = -0.53/1 = -0.53

then the point-slope form of the equation of the line can be written as

y = m(x -h) +k . . . . . m = -0.53, (h, k) = (0, 62.33)

y = -0.53x +62.33 . . . x = years after 2004

part b. in 2017, x = 2017 -2004 = 13. then the predicted rainfall is

y = -0.53·13 +62.33 = 55.44 . . inches

the predicted rainfall in 2017 is 55.44 in.
